Included with the Hamlib distribution are several utility programs.
Besides providing a way for developers to test new code and bug fixes,
the programs also offer a reference implementation for interfacing to
the Hamlib library functions both through the C API and offering a
network accessible API.
This chapter focuses on the two test programs, @command{rigctl} for
testing radio back ends and @command{rotctl} for testing rotor back
ends and the two network daemons, @command{rigctld} and
@command{rotcltd} for radio and rotor access via network sockets.

@command{rigctl} is the most frequently used Hamlib utility. As the
other utilities share many of the same characteristics, much of the
introductory information presented in this section is applicable to
the other utility programs.

@subsection Introduction to @command{rigctl}
@cindex Introduction to @command{rigctl}
@cindex @command{rigctl}, introduction to
Most likely the first of the Hamlib utility programs that is used is
@command{rigctl}. @command{rigctl} is a character based interactive
program and a command line program able to set or query a radio's
value with a single command. @command{rigctl} is invoked from a shell
command prompt with various options and additional commands.
In its most simple use as a @dfn{command line} program,
@command{rigctl} is used to set frequency and mode by typing commands
after any @command{rigctl} options:
@example
@kbd{rigctl F 14205000}
@kbd{rigctl M USB 2400}
@end example
@noindent
and then query those values:
@example
@kbd{rigctl f}
@kbd{rigctl m}
@end example
Entering interactive mode is a simple matter of not placing any
commands after any @command{rigctl} options:
@example
@kbd{rigctl}
@end example
@noindent
Entering @dfn{interactive mode} allows successive commands to be
entered without exiting @command{rigctl}. Recent additions to
@command{rigctl} allow command editing and history recall through use
of the @url{ http://cnswww.cns.cwru.edu/php/chet/readline/rltop.html,
Readline} library.
Interactive mode is indicated by the spartan prompt:
@example
Rig command:
@end example
@noindent
Commands are given at the prompt and follow the general rule that
upper case letters set a value and lower case letters query a value:
@example
Rig command: @kbd{M}
Mode: @kbd{USB}
Passband: @kbd{2500}
Rig command: @kbd{m}
Mode: USB
Passband: 2500
Rig command:
@end example
An additional prompt is printed when more information is required by
the command. For @kbd{M} above, @command{rigctl} prompted for the
``Mode'' and ``Passband'' values. For @kbd{m} above, @command{rigctl}
returned the ``Mode'' and ``Passband'' values without further prompts.
The command prompt is returned after each command invocation.
The above examples invoked @command{rigctl} without specifying a radio
model. This is a feature where the Hamlib internal radio @dfn{dummy} is
used instead. The dummy radio provides a way to test Hamlib functions
with out the need for actual radio hardware. However, to develop back
end capability for a given radio, having the actual radio connected to
the computer is necessary for debugging.
For example, to quickly set frequency on an Elecraft K3:
@example
@kbd{rigctl -m 229 -r /dev/rig F 3900000}
@end example
@noindent
and to query the frequency and then mode:
@example
@kbd{rigctl -m 229 -r /dev/rig f}
3900000
@kbd{rigctl -m 229 -r /dev/rig m}
LSB
2000
@end example
@noindent
The returned values do not have the prompt strings associated with
interactive mode as shown above.
The @option{-m} option takes a numeric value that corresponds to a
given radio back end model. The @option{-r} option takes the path to
the port device on @acronym{POSIX} and the device name on MS Windows.
@quotation Note
A complete list of supported radio models may be seen by use of the
@option{-l} option:
@example
@kbd{rigctl -l}

the list. The list is sorted numerically by model number since Hamlib
1.2.15.1. Model numbers of a manufacturer/ protocol family are
grouped together.

@node rigctl invocation
@subsection @command{rigctl} invocation
@cindex @command{rigctl} invocation
@cindex invocation, @command{rigctl}
Here are some additional examples for invoking @command{rigctl} for
various situations.
@noindent
Start @command{rigctl} for a Yaesu FT-920 using a @acronym{USB} to serial
adapter on Linux in interactive mode:
@example
rigctl -m 114 -r /dev/ttyUSB1
@end example
@noindent
Start @command{rigctl} for a Yaesu FT-920 using @file{COM1} on MS
Windows while generating TRACE output to @file{stderr}:
@example
rigctl -m 114 -r COM1 -vvvvv
@end example
@noindent
Start @command{rigctl} for a Yaesu FT-920 using a @acronym{USB} to
serial adapter on Linux while setting baud rate and stop bits:
@example
rigctl -m 114 -r /dev/ttyUSB1 -s 4800 -C stop_bits=2
@end example
@noindent
Start @command{rigctl} for an Elecraft K3 using a @acronym{USB} to
serial adapter on Linux while specifying a command terminator for the
@command{w} command:
@example
rigctl -m 229 -r /dev/ttyUSB0 -t';'
@end example
@noindent
Connect to a running @command{rigctld} with radio model 2 (@code{NET
rigctl}) on the local host and specifying the @acronym{TCP} port,
setting frequency and mode:
@example
rigctl -m 2 -r localhost:4532 F 7253500 M LSB 0
@end example
@strong{N.B.} On MS Windows @kbd{localhost} may need to be replaced
with the actual loopback @acronym{IP} address--@kbd{127.0.0.1}--or the
address passed to @command{rigctld} with the @option{-T} option.
@node rigctl command line options
@subsection @command{rigctl} command line options
@cindex @command{rigctl} command line options
@cindex Command line options, @command{rigctl}
The @command{rigctl} command line options (not to be confused with
@command{rigctl} commands) control the action of various features.
Options consist of both ``short options''--a single hyphen '@kbd{-}'
followed by a single letter and ``long options''--two hyphens
'@kbd{--}' followed by several letters often comprising one or more
words separated by a hyphen.
@command{rigctl} accepts the following options:
@table @option
@item -m
@itemx --model=@var{id}
Select radio model number. See model list (use @kbd{rigctl -l}).
@strong{N.B.} @command{rigctl} (or third party software) will use rig
model 2 for NET rigctl (@command{rigctld}).
@item -r
@itemx --rig-file=@var{device}
Use @var{device} as the file name of the port the radio is connected.
Often a serial port, but could be a USB to serial adapter. Typically
@file{/dev/ttyS0} , @file{/dev/ttyS1} , @file{/dev/ttyUSB0} , etc.@:
on Linux or @file{COM1} , @file{COM2} , etc.@: on MS Windows.
@ifhtml
@*
@end ifhtml
@item -p
@itemx --ptt-file=@var{device}
Use @var{device} as the file name of the Push-To-Talk device using a
device file as described above.
@ifhtml
@*
@end ifhtml
@item -d
@itemx --dcd-file=@var{device}
Use @var{device} as the file name of the Data Carrier Detect device
using a device file as described above.
@ifhtml
@*
@end ifhtml
@item -P
@itemx --ptt-type=@var{type}
Use @var{type} of Push-To-Talk device. Supported types are
@code{RIG}, @code{DTR}, @code{RTS}, @code{PARALLEL}, @code{NONE},
overriding @acronym{PTT} type defined in the rig's backend.
Some side effects of this command are that when type is set to
@code{DTR}, read @acronym{PTT} state comes from Hamlib frontend, not
read from the radio. When set to @code{NONE}, @acronym{PTT} state
cannot be read or set even if rig backend supports reading/setting
@acronym{PTT} status from the rig.
@item -D
@itemx --dcd-type=@var{type}
Use @var{type} of Data Carrier Detect device. Supported types are
@code{RIG} (@acronym{CAT} command), @code{DSR}, @code{CTS}, @code{CD},
@code{PARALLEL}, @code{NONE}.
@ifhtml
@*
@end ifhtml
@item -s
@itemx --serial-speed=@var{baud}
Set serial speed to @var{baud} rate. Uses @strong{maximum} serial
speed from rig backend capabilities (set by @option{-m} above) as the
default.
@ifhtml
@*
@end ifhtml
@item -c
@itemx --civaddr=@var{id}
Use @var{id} as the @acronym{CI-V} address to communicate with the
rig. Only useful for Icom radios and those using the Icom protocol.
@strong{N.B.} The @var{id} is in decimal notation, unless prefixed by
@code{0x}, in which case it is a hexadecimal value.
@item -t
@itemx --send-cmd-term=@var{char}
Change the termination @var{char} for text protocol when using the
@code{send_cmd} command. The default value is @code{<CR>}
(@code{0x0d}). Non @acronym{ASCII} printable characters can be
specified as an @acronym{ASCII} number, in hexadecimal format,
prepended with @code{0x}. You may pass an empty string for no
termination char. The string '@code{-1}' tells @command{rigctl} to
switch to binary protocol. See the @code{send_cmd} command for further
explanation.
@ifhtml
@*
@end ifhtml
@item -L
@itemx --show-conf
List all config parameters for the radio defined with @option{-m}
above.
@ifhtml
@*
@end ifhtml
@item -C
@itemx --set-conf=@var{parm}=@var{val}[,@var{parm}=@var{val},@dots{}]
Set config parameter. e.g.@: @code{stop_bits=2}
Use @option{-L} option for a list.
@item -l
@itemx --list

scrollbars of a virtual terminal in X or the @command{cmd} window in
MS Windows. The output can be piped to '@command{more}' or
'@command{less}', e.g.@: '@kbd{rigctl -l | more}'.
@item -u
@itemx --dump-caps
Dump capabilities for the radio defined with @option{-m} above and
exit.
@ifhtml
@*
@end ifhtml
@item -o
@itemx --vfo
Set vfo mode, requiring an extra @acronym{VFO} argument in front of
each appropriate command (except @command{set_vfo}!). Otherwise,
@code{currVFO} is assumed when this option is not set and an extra VFO
argument is not used. See @command{chk_vfo} below.
@ifhtml
@*
@end ifhtml
@item -n
@itemx --no-restore-ai
On exit @command{rigctl} restores the state of auto information (AI)
on the controlled rig. If this is not desired, for example if you are
using @command{rigctl} to turn AI mode on or off, pass this option.
@item -i
@itemx --read-history
Read previously saved command and argument history from a file
(default '@file{$HOME/.rigctl_history}') for the current session.
Available when @command{rigctl} is built with Readline support.
@strong{N.B.} To read a history file stored in another directory, set
the @env{RIGCTL_HIST_DIR} environment variable, e.g.@:
'@kbd{RIGCTL_HIST_DIR=$HOME/tmp rigctl -i}'. When
@env{RIGCTL_HIST_DIR} is not set, the value of @env{HOME} is used.
@item -I
@itemx --save-history
Write current session (and previously saved session(s) if @option{-i}
option is also given) command and argument history to a file (default
'@file{$HOME/.rigctl_history}') at the end of the current session.
Complete commands with arguments are saved as a single line to be
recalled and used or edited. Available when @command{rigctl} is built
with Readline support.
To write a history file in another directory, set the
@env{RIGCTL_HIST_DIR} environment variable, e.g.@:
'@kbd{RIGCTL_HIST_DIR=$HOME/tmp rigctl -I}'. When
@env{RIGCTL_HIST_DIR} is not set, the value of @env{HOME} is used.
@item -v
@itemx --verbose
Set verbose mode level, cumulative i.e.@: @option{-vvvvv} sets maximum
debugging output to @file{stderr}.
Five different levels of diagnostics can be output to @file{stderr}
and correspond to @option{-v} for @code{BUG}, @option{-vv} for
@code{ERR}, @option{-vvv} for @code{WARN}, @option{-vvvv} for
@code{VERBOSE}, or @option{-vvvvv} for @code{TRACE}. Back end authors
will use the verbose facility to print critical values useful for
testing and will often ask for this output in response to a request
for help.
@item -h
@itemx --help
Show summary of these options and exit.
@ifhtml
@*
@end ifhtml
@item -V
@itemx --version
Show version of @command{rigctl} and exit.
@end table
@quotation Note
Some options may not be implemented by a given backend and will return
an error. This is most likely to occur with the @option{--set-conf}
and @option{--show-conf} options.
@end quotation
@node rigctl commands
@subsection @command{rigctl} commands
@cindex @command{rigctl} commands
@cindex commands, @command{rigctl}
Commands can be entered either as a single char, or as a long command
name. Basically, the commands do not take a dash in front of them on
the command line, as the options do. They may be typed in when in
interactive mode or provided as argument(s) in command line interface
mode. In interactive mode commands and their arguments may be entered
on a single line:
@example
Rig command: M LSB 2400
@end example
@noindent
or singly and @command{rigctl} will prompt for any needed values.
Since most of the Hamlib operations have a ``set'' and a ``get''
method, in general an upper case letter will be used for set methods
whereas the corresponding lower case letter refers to the get method.
Each operation also has a long name; prepend a backslash @kbd{\} to
enter a long command name.
@quotation
Example: Use @kbd{\dump_caps} to see what this radio can do.
@end quotation
@noindent
Be aware that the backend for the radio to be controlled, or the radio
itself may not support some commands. In that case, the operation will
fail with a Hamlib error message.
Here is a summary of the supported commands:
@itemize
@item
Command short name is followed by the long name which is followed by
any variable names.
@item
Some short commands are noted as hexadecimal digits due to the
limitation of upper and lower case letters available. Use the
associated long command name instead.
@item
While a comma is used to separate variable names in this document,
they are not part of the command syntax used by @command{rigctl}. Use
a space to separate values.
@item
In the case of ``set'' commands the variable @var{name} is replaced by
the value in the description.
@item
In the case of ``get'' commands the variable @var{name} is the key
name of the value returned.
@end itemize
@table @command
@item q
Exit @command{rigctl} in interactive mode (@kbd{q} is not case
sensitive).
When @command{rigctl} is controlling the rig directly, will close the
rig back end and port. When @command{rigctl} is connected to
@command{rigctld} (rig model 2), the @acronym{TCP/IP} connection to
@command{rigctld} is closed and @command{rigctld} remains running,
available for another @acronym{TCP/IP} network connection.
@item F, set_freq @var{Frequency}

rig passband unchanged from the current or default value for the mode
as defined by the rig.
@strong{N.B.} Passing a @kbd{?} (query) as the first argument
instead of @var{Mode} will return a space separated list of radio
backend supported Modes. Use this to determine the supported Modes of
a given radio backend.

This is a convenience function that combines the effect of
@command{set_split_freq} and @command{set_split_mode}. It should be
used when both are required since it allows the back end to optimize
the operations. For example on many Icom rigs the current VFO must be
changed temporarily while executing these commands and that can

@node rigctl readline support
@subsection @command{rigctl} Readline support
@cindex @command{rigctl} Readline support
@cindex Readline support, @command{rigctl}
If Readline library development files are found at configure time,
@command{rigctl} will be conditonally built with Readline support for
command and argument entry. Readline command key bindings are at
their defaults as described in the
@url{http://cnswww.cns.cwru.edu/php/chet/readline/rluserman.html,
Readline manual} although @command{rigctl} sets the name @code{rigctl}
which can be used in @code{Conditional Init Constructs} in the
Readline Init File (@file{$HOME/.inputrc} by default) for custom
keybindings unique to @command{rigctl}.
Command history is available with Readline support as described in the
@url{http://cnswww.cns.cwru.edu/php/chet/readline/history.html#SEC1,
Readline History manual}. Command and argument strings are stored as
single lines even when arguments are prompted for input individually.
Commands and arguments are not validated and are stored as typed with
values separated by a single space.
Normally session history is not saved, however, use of either of the
@option{-i}/@option{--read-history} or
@option{-I}/@option{--save-history} options when starting
@command{rigctl} will cause any previously saved history to be read in
and/or the current and any previous session history (assuming the
@option{-i} and @option{-I} options are given together) will be
written out when @command{rigctl} is closed. Each option is mutually
exclusive, i.e. either may be given separately or in combination.
This is useful to save a set of commands and then read them later but
not write the modified history for a consistent set of test commands
in interactive mode, for example.
History is stored in @file{$HOME/.rigctl_history} by default although
the destination directory may be changed by setting the
@env{RIGCTL_HIST_DIR} environment variable. When
@env{RIGCTL_HIST_DIR} is unset, the value of the @env{HOME}
environment variable is used instead. Only the destination directory
may be changed at this time.
If Readline support is not found at configure time the original
internal command handler is used. Readline is not used for
@command{rigctl} commands entered on the command line regardless if
Readline support is built in or not.
@quotation Note
Readline support is not included in the MS Windows 32 binary builds
supplied by the Hamlib Project. Running @command{rigctl} on the MS
Windows 32 platform in the @command{cmd} shell does give session
command line history, however, it is not saved to disk between
sessions.

@cindex rotctl
Identical in function to @command{rigctl}, @command{rotctl} provides a
means for testing Hamlib functions useful for rotor control and
@acronym{QRA} locator computations. As rotors have a much narrower

@node Introduction to rotctl
@subsection Introduction to @command{rotctl}
@cindex Introduction to @command{rotctl}
@cindex @command{rotctl}, introduction to
@command{rotctl} is a character based interactive program and a
command line program able to set or query a rotor's value with a
single command. @command{rotctl} is invoked from a shell command
prompt with various options and additional commands.
In its most simple use as a command line program, @command{rotctl} is
used to set frequency and mode by typing commands after any
@command{rotctl} options:
@example
@kbd{rotctl P 145.0 23.0}
@kbd{rotctl M 8 25}
@end example
@noindent
and then query those values:
@example
@kbd{rotctl p}
@end example
Entering interactive mode is a simple matter of not placing any
commands after any @command{rotctl} options:
@example
@kbd{rotctl}
@end example
@noindent
Entering interactive mode allows successive commands to be entered
without exiting @command{rotctl}. Recent additions to
@command{rotctl} allow command editing and history recall through use
of the @url{ http://cnswww.cns.cwru.edu/php/chet/readline/rltop.html,
Readline} library.
Interactive mode is indicated by the spartan prompt:
@example
Rotator command:
@end example
@noindent
Commands are given at the prompt:
@example
Rotator command: @kbd{M}
Direction: 16
Speed: 60
Rotator command: @kbd{p}
Azimuth: 11.352000
Elevation: 0.000000
Rotator command: @kbd{p}
Azimuth: 27.594000
Elevation: 0.000000
Rotator command:
@end example
An additional prompt is printed when more information is required by
the command. For @kbd{M} above, @command{rotctl} prompted for the
``Direction'' and ``Speed'' values. For @kbd{p} above, @command{rotctl}
returned the ``Azimuth'' and ``Elevation'' values without further prompts.
The command prompt is returned after each command invocation.
The above examples invoked @command{rotctl} without specifying a rotor
model. This is a feature where the Hamlib internal rotor dummy is
used instead. The dummy rotor provides a way to test Hamlib functions
with out the need for actual rotor hardware. However, to develop back
end capability for a given rotor, having the actual radio connected to
the computer is necessary for debugging.
For example, to quickly set position for RotorEZ:
@example
@kbd{rotctl -m 401 -r /dev/rotor P 100.0 0.0}
@end example
@noindent
and to query the position:
@example
@kbd{rotctl -m 401 -r /dev/rotor p}
100.000000
0.000000
@end example
@noindent
The returned values do not have the prompt strings associated with
interactive mode as shown above.
The @option{-m} option takes a numeric value that corresponds to a
given rotor back end model. The @option{-r} option takes the path to
the port device on @acronym{POSIX} and the device name on MS Windows.
@quotation Note
A complete list of supported radio models may be seen by use of the
@option{-l} option:
@example
@kbd{rotctl -l}

@noindent
The list is long so use @kbd{@key{SHIFT}-PageUp}/
@kbd{@key{SHIFT}-PageDown} on Linux, @kbd{@key{ScrollLock}} then
@kbd{@key{PageUp}}/@kbd{@key{PageDown}} on Free BSD, or use the

Windows) or the output can be piped to '@command{more}' or
'@command{less}', e.g.@: '@kbd{rotctl -l | more}' to scroll back up
the list. The list is sorted numerically by model number since Hamlib
1.2.15.1. Model numbers of a manufacturer/ protocol family are
grouped together.

azimuth conversions.
@table @command
@item L, lonlat2loc @var{Longitude}, @var{Latitude}, @var{Loc Len 2..12}
Returns the Maidenhead locator for the given @var{Longitude} and
@var{Latitude}.
Both are floating point values. The precision of the returned square
is controlled by @var{Loc Len} which should be an even numbered
integer value between @code{2} and @code{12}.
For example, @kbd{L -170.000000 -85.000000 12} returns @samp{Locator:
AA55AA00AA00}.
@item l, loc2lonlat @var{Locator}
Returns @var{Longitude} and @var{Latitude} in decimal degrees at the
approximate center of the requested grid square (despite the use of
double precision variables internally, some rounding error occurs).
West longitude is expressed as a negative value. South latitude is
expressed as a negative value. Locator can be from 2 to 12 characters
in length.
For example, @kbd{l AA55AA00AA00} returns @samp{Longitude: -169.999983
Latitude: -84.999991}.

@node rotctl readline support
@subsection @command{rotctl} Readline support
@cindex @command{rotctl} Readline support
@cindex Readline support, @command{rotctl}
If Readline library development files are found at configure time,
@command{rotctl} will be conditonally built with Readline support for
command and argument entry. Readline command key bindings are at
their defaults as described in the
@url{http://cnswww.cns.cwru.edu/php/chet/readline/rluserman.html,
Readline manual} although @command{rotctl} sets the name @code{rotctl}
which can be used in @code{Conditional Init Constructs} in the
Readline Init File (@file{$HOME/.inputrc} by default) for custom
keybindings unique to @command{rotctl}.
Command history is available with Readline support as described in the
@url{http://cnswww.cns.cwru.edu/php/chet/readline/history.html#SEC1,
Readline History manual}. Command and argument strings are stored as
single lines even when arguments are prompted for input individually.
Commands and arguments are not validated and are stored as typed with
values separated by a single space.
Normally session history is not saved, however, use of either of the
@option{-i}/@option{--read-history} or
@option{-I}/@option{--save-history} options when starting
@command{rotctl} will cause any previously saved history to be read in
and/or the current and any previous session history (assuming the
@option{-i} and @option{-I} options are given together) will be
written out when @command{rotctl} is closed. Each option is mutually
exclusive, i.e. either may be given separately or in combination.
This is useful to save a set of commands and then read them later but
not write the modified history for a consistent set of test commands
in interactive mode, for example.
History is stored in @file{$HOME/.rotctl_history} by default although the
destination directory may be changed by setting the
@env{ROTCTL_HIST_DIR} environment variable. When
@env{ROTCTL_HIST_DIR} is unset, the value of the @env{HOME} environment
variable is used instead. Only the destination directory may be
changed at this time.
If Readline support is not found at configure time the original
internal command handler is used. Readline is not used for
@command{rotctl} commands entered on the command line regardless if
Readline support is built in or not.
@quotation Note
Readline support is not included in the MS Windows 32 binary builds
supplied by the Hamlib Project. Running @command{rotctl} on the MS
Windows 32 platform in the @command{cmd} shell does give session
command line history, however, it is not saved to disk between
sessions.

@cindex rigctld
The @command{rigctld} program is a network server that accepts the
familiar commands of @command{rigctl} and provides the response data
over a @acronym{TCP/IP} network socket to an application. In this
manner an application can access a @command{rigctl} instance from
nearly anywhere (caveat, no security is currently provided by
@command{rigctl}). Applications using @command{rigctl} do not link to
Hamlib nor use its C API.

@node Introduction to rigctld
@subsection Introduction to @command{rigctld}
@cindex Introduction to @command{rigctld}
@cindex @command{rigctld}, introduction to
Multiple radios can be controlled on different @acronym{TCP} ports by
use of multiple @command{rigctld} processes. The syntax of the
commands are the same as @command{rigctl}. It is hoped that
@command{rigctld} will be especially useful for client authors using
languages such as @url{http://www.perl.org/, Perl},
@url{http://www.python.org/, Python}, @url{http://php.net/, PHP},
@url{http://www.ruby-lang.org/en/, Ruby}, @url{http://www.tcl.tk/,
TCL}, and others.
@command{rigctld} communicates to a client through a @acronym{TCP}
network socket using text commands shared with @command{rigctl}. The
protocol is simple; commands are sent to @command{rigctld} on one line
and @command{rigctld} responds to ``get'' commands with the requested
values, one per line, when successful, otherwise, it responds with one
line @samp{RPRT x}, where @samp{x} is a negative number indicating the
Hamlib error code. Commands that do not return values respond with
the line @samp{RPRT x}, where @samp{x} is zero when successful,
otherwise a regative number indicating the Hamlib error code. Each
line is terminated with a newline @code{\n} character. This protocol
is primarily for use by the @code{NET rigctl} (rig model 2) backend.
@xref{rigctld Default protocol}.
A separate Extended Response protocol extends the above behavior by
echoing the received command string as a header, any returned values
as a key: value pair, and the @samp{RPRT x} string as the end of
response marker which includes the Hamlib success or failure value.
Consider using this protocol for clients that will interact with
@command{rigctld} directly through a @acronym{TCP} network socket.
@xref{rigctld Extended Response protocol}.
@node rigctld invocation
@subsection @command{rigctld} invocation
@cindex @command{rigctld} invocation
@cindex invocation, @command{rigctld}
The command line invocation for @command{rigctld} is similar to
@command{rigctl} except that in POSIX environments a trailing @kbd{&}
is appended to the command string to ``background'' the
@command{rigctld} process so the shell can be used to run other
commands while @command{rigctld} continues to run.
Here are some examples for invoking @command{rigctld}.
Start @command{rigctld} for a Yaesu FT-920 using a USB-to-serial
adapter and backgrounding:
@example
rigctld -m 114 -r /dev/ttyUSB1 &
@end example
Start @command{rigctld} for a Yaesu FT-920 using a USB to serial
adapter while setting baud rate and stop bits, and backgrounding:
@example
rigctld -m 114 -r /dev/ttyUSB1 -s 4800 -C stop_bits=2 &
@end example
Start @command{rigctld} for an Elecraft K3 using @code{COM2} on MS
Windows:
@example
rigctld -m 229 -r COM2 -T 127.0.0.1 -t 4532
@end example
@quotation Note
On MS Windows the use of the @option{-T} and @option{-t} options appear
to be necessary to set the @acronym{IP} address and @acronym{TCP} port
or else the network socket cannot be found. On @acronym{POSIX} systems
the @command{rigctld} default values will be used.
@end quotation
Connect to the already running @command{rigctld}, and set current
frequency to 14.266 MHz with a 1 second read timeout using the default
protocol from the shell prompt:
@example
echo "\set_freq 14266000" | nc -w 1 localhost 4532
@end example
Connect to a running @command{rigctld} with @command{rigctl} on the
local host:

@item -r
@itemx --rig-file=@var{device}
Use @var{device} as the file name of the port the radio is connected.
Often a serial port, but could be a USB to serial adapter. Typically
@file{/dev/ttyS0} , @file{/dev/ttyS1} , @file{/dev/ttyUSB0} , etc.@:

@itemx --ptt-type=@var{type}
Use @var{type} of Push-To-Talk device. Supported types are
@code{RIG}, @code{DTR}, @code{RTS}, @code{PARALLEL}, @code{NONE},
overriding @acronym{PTT} type defined in the rig's backend.
Some side effects of this command are that when type is set to
@code{DTR}, read @acronym{PTT} state comes from Hamlib frontend, not
read from the radio. When set to @code{NONE}, @acronym{PTT} state
cannot be read or set even if rig backend supports reading/setting
@acronym{PTT} status from the rig.
@item -D
@itemx --dcd-type=@var{type}
Use @var{type} of Data Carrier Detect device. Supported types are

@node rigctld commands
@subsection @command{rigctld} commands
@cindex @command{rigctld} commands
@cindex commands, @command{rigctld}
Commands can be sent over the @acronym{TCP} socket either as a single
char, or as a long command name plus the value(s) space separated on
one @code{\n} terminated line. @xref{rigctld protocol}.
Since most of the Hamlib operations have a ``set'' and a ``get''
method, in general an upper case letter will be used for set methods
whereas the corresponding lower case letter refers to the get method.
Each operation also has a long name; in interactive mode, prepend a
backslash @kbd{\} to enter a long command name.
Example (Perl):
@example
print $socket "\\dump_caps\n";
@end example
@noindent
to see what the radio's backend can do.
@quotation N.B.
In Perl and many other languages a @kbd{\} will need to
be escaped with a preceding @kbd{\} so that even though two backslash
characters appear in the code, only one will be passed to
@command{rigctld}. This is a possible bug, so beware!
@end quotation
Be aware that the backend for the radio to be controlled, or the radio
itself may not support some commands. In that case, the operation will
fail with a Hamlib error message.
Here is a summary of the supported commands:
@itemize
@item
Command short name is followed by the long name which is followed by
any variable names.
@item
Some short commands are noted as hexadecimal digits due to the
limitation of upper and lower case letters available. Use the
associated long command name instead.
@item
While a comma is used to separate variable names in this document,
they are not part of the command syntax used by @command{rigctl}. Use
a space to separate values.
@item
In the case of ``set'' commands the variable @var{name} is replaced by
the value in the description.
@item
In the case of ``get'' commands the variable @var{name} is the key
name of the value returned.

@node rigctld protocol
@subsection @command{rigctld} protocol
@cindex @command{rigctld} protocol
@cindex protocol, @command{rigctld}
Two protocols exist for communicating with @command{rigctld}. The
``Default'' protocol is primarily used internally by Hamlib so an
application that is not written to use @command{rigctld} directly via
@acronym{TCP} network sockets can still access @command{rigctld}. The
other ``Extended Response Protocol'' is intended for the more general
use case where a variety of response formats may be needed.
@menu
* rigctld Default protocol::
* rigctld Extended Response protocol::
@end menu
@node rigctld Default protocol
@subsubsection @command{rigctld} Default protocol
@cindex @command{rigctld} Default protocol
@cindex Default protocol, @command{rigctld}
The @command{rigctld} protocol is intentionally simple. Commands are
entered on a single line with any needed values. In Perl, for exampl,
reliable results are obtained by terminating each command string with
a newline character, @samp{\n}.
@noindent
Example @code{set} (Perl code):
@example
print $socket "F 14250000\n";
print $socket "\\set_mode LSB 2400\n"; # escape leading '\'
@end example
@noindent
A one line response will be sent as a reply to @code{set} commands,
@samp{RPRT x\n} where @samp{x} is the Hamlib error code with @samp{0}
indicating success of the command.
@noindent
Responses from @command{rigctld} get commands are text values and
match the same tokens used in the @code{set} commands. Each value
is returned on its own line. On error the string @samp{RPRT x\n} is
returned where @samp{x} is the Hamlib error code.
@noindent
Example @code{get} (Perl code):
@example
print $socket "f\n";
"14250000\n"
@end example
@noindent
Most @code{get} functions return one to three values. A notable
exception is the @command{dump_caps} command which returns many lines
of @samp{key:value} pairs.
This protocol is primarily used by the @code{NET rigctl}
(@command{rigctl} model 2) backend which allows applications already
written for Hamlib's C @acronym{API} to take advantage of
@command{rigctld} without the need of rewriting application code. An
application's user can select rig model 2 (@code{NET rigctl}) and then
set @option{rig_pathname} to @kbd{localhost:4532} or other network
host:port (set by the @option{-t} option above).
@node rigctld Extended Response protocol
@subsubsection @command{rigctld} Extended Response Protocol
@cindex @command{rigctld} Extended Response Protocol
@cindex Extended Response Protocol, @command{rigctld}
An EXPERIMENTAL Extended Response protocol has been introduced into
@command{rigctld} as of February 16, 2010. This protocol adds several
rules to the strings returned by @command{rigctld} and adds a rule for
the command syntax.
@enumerate
@item
The command received by @command{rigctld} is echoed with its long
command name followed by the value(s) (if any) received from the
client terminated by the specified response separator as the record
line of the response.
@item
The last line of each block is the string @samp{RPRT x\n} where
@samp{x} is the numeric return value of the Hamlib backend function
that was called by the command.
@item
Any records consisting of data values returned by the rig backend are
prepended by a string immediately followed by a colon then a space and
then the value terminated by the response
separator. e.g. @samp{Frequency: 14250000\n} when the command was
prepended by @code{+}.
@item
All commands received will be acknowledged by @command{rigctld} with
lines from rules 1 and 2. Lines from rule 3 are only returned when
data values must be returned to the client.
@end enumerate
An example response to a @command{+\set_mode} command sent from the
shell prompt (note the prepended @code{+}):
@example
echo "+M USB 2400" | nc -w 1 localhost 4532
set_mode: USB 2400
RPRT 0
@end example
In this case the long command name and values are returned on the
first line and the second line contains the end of block marker and
the numeric rig backend return value indicating success.
An example response to a @command{\get_mode} query:
@example
echo "+\get_mode" | nc -w 1 localhost 4532
get_mode:
Mode: USB
Passband: 2400
RPRT 0
@end example
In this case, as no value is passed to @command{rigctld}, the first
line consists only of the long command name. The final line shows
that the command was processed successfully by the rig backend.
Invoking the Extended Response protocol requires prepending a command
with a punctuation character. As shown in the examples above,
prepending a '@code{+} character to the command results in the
responses being separated by a newline character (@samp{\n}). Any
other punctuation character recognized by the C @code{ispunct()}
function except @code{\}, @code{?}, or @code{_} will cause that
character to become the response separator and the entire response
will be on one line.
Separator character summary:
@table @code
@item +
Each record of the response is appended with a newline (@samp{\n}).
@ifhtml
@*
@end ifhtml
@item ;, |, or ,
Each record of the response is appended by the given character
resulting in entire response on one line.
Common record separators for text representations of spreadsheet data,
etc.
@item ?
Reserved for 'help' in @command{rigctl} short command.
@ifhtml
@*
@end ifhtml
@item _
Reserved for @command{\get_info} in @command{rigctl} short command.
@ifhtml
@*
@end ifhtml
@item #
Reserved for comments when reading a command file script.
@end table
Other punctuation characters have not been tested! Use at your own
risk.
For example, invoking a @command{;\get_mode} query with a leading
@code{;} returns:
@example
get_mode:;Mode: USB;Passband: 2400;RPRT 0
@end example
Or, using the vertical bar (pipe) character @code{|} returns:
@example
get_mode:|Mode: USB|Passband: 2400|RPRT 0
@end example
And a @command{\set_mode} command prepended with a @code{|} returns:
@example
set_mode: USB 2400|RPRT 0
@end example
Such a format will allow reading a response as a single event using a
preferred response separator. Other punctuation characters have not
been tested!
@node rotctld
@section @command{rotctld}
@cindex rotctld
The @command{rotctld} program is a network server that accepts the
familiar commands of @command{rotctl} and provides the response data
over a @acronym{TCP/IP} network socket to an application. In this
manner an application can access a @command{rotctl} instance from
nearly anywhere (caveat, no security is currently provided by
@command{rotctl}). Applications using @command{rotctl} do not link to
Hamlib nor use its C API.

@node Introduction to rotctld
@subsection Introduction to @command{rotctld}
@cindex Introduction to @command{rotctld}
@cindex @command{rotctld}, introduction to
@command{rotctld} communicates to a client through a @acronym{TCP}
socket using text commands shared with @command{rotctl}. The protocol
is simple, commands are sent to @command{rotctld} on one line and
@command{rotctld} responds to ``get'' commands with the requested
values, one per line, when successful, otherwise, it responds with one
line @samp{RPRT x}, where @samp{x} is a negative number indicating the
error code. Commands that do not return values respond with the line
@samp{RPRT x}, where @samp{x} is zero when successful, otherwise is a
regative number indicating the error code. Each line is terminated
with a newline @code{\n} character. This protocol is primarily for
use by the @code{NET rotctl} (rot model 2) backend. @xref{rotctld
Default protocol}.
A separate Extended Response protocol extends the above behavior by
echoing the received command string as a header, any returned values
as a key: value pair, and the @samp{RPRT x} string as the end of
response marker which includes the Hamlib success or failure value.
Consider using this protocol for clients that will interact with
@command{rotctld} directly through a @acronym{TCP} network socket.
@xref{rotctld Extended Response protocol}.
@node rotctld invocation
@subsection @command{rotctld} invocation
@cindex @command{rotctld} invocation
@cindex invocation, @command{rotctld}
The command line invocation for @command{rotctld} is similar to
@command{rotctl} except that in POSIX environments a trailing @kbd{&}
is appended to the command string to ``background'' the
@command{rotctld} process so the shell can be used to run other
commands while @command{rotctld} continues to run.
Here are some examples for invoking @command{rotctld}.
Start @command{rotctld} for a Ham IV rotor with the RotorEZ installed
using a USB-to-serial adapter and backgrounding:
@example
rotctld -m 401 -r /dev/ttyUSB1 &
@end example
Start @command{rotctld} for RotorEZ using @code{COM2} on MS Windows:
@example
rotctl -m 401 -r COM2 -T 127.0.0.1 -t 4533
@end example
@quotation Note
On MS Windows the use of the @option{-T} and @option{-t} options appear
to be necessary to set the @acronym{IP} address and @acronym{TCP} port
or else the network socket cannot be found. On @acronym{POSIX} systems
the @command{rotctld} default values will be used.
@end quotation
Connect to the already running rotctld, and set position to 135.0
degrees azimuth and 30.0 degrees elevation with a 1 second read
timeout from the shell prompt:
@example
echo "\set_pos 135.0 30.0" | nc -w 1 localhost 4533
@end example
Connect to a running @command{rotctld} with @command{rotctl} on the
local host:
@example

@node rotctld commands
@subsection @command{rotctld} commands
@cindex @command{rotctld} commands
@cindex commands, @command{rotctld}
Commands can be sent over the @acronym{TCP} socket either as a single
char, or as a long command name plus the value(s) space separated on
one @code{\n} terminated line. @xref{rotctld protocol}.
Since most of the Hamlib operations have a ``set'' and a ``get''
method, in general an upper case letter will be used for set methods
whereas the corresponding lower case letter refers to the get method.
Each operation also has a long name; in interactive mode, prepend a
backslash @kbd{\} to enter a long command name.
Example (Perl):
@example
print $socket "\\dump_caps\n";
@end example
@noindent
to see what the rotor's backend can do.
@quotation N.B.
In Perl and many other languages a @kbd{\} will need to
be escaped with a preceding @kbd{\} so that even though two backslash
characters appear in the code, only one will be passed to
@command{rotctld}. This is a possible bug, so beware!
@end quotation
Be aware that the backend for the rotor to be controlled, or the rotor
itself may not support some commands. In that case, the operation will
fail with a Hamlib error message.
@strong{Rotor commands}
Here is a summary of the supported commands:

At the moment returns @var{Model Name}.
@item w, send_cmd @var{Cmd}
Send raw command string to the rotator.
@code{<CR>} (or @option{send-cmd-term}, see @option{-t} option) is
appended automatically at the end of the command for text protocols.
For binary protocols, enter values as @code{\0xAA\0xBB}.

@strong{Locator Commands}
These commands offer conversions of Degrees Minutes Seconds to other
formats, Maidenhead square locator conversions and distance and
azimuth conversions.
@table @command
@item L, lonlat2loc @var{Longitude}, @var{Latitude}, @var{Loc Len 2..12}
Returns the Maidenhead locator for the given @var{Longitude} and
@var{Latitude}.
Both are floating point values. The precision of the returned square
is controlled by @var{Loc Len} which should be an even numbered
integer value between @code{2} and @code{12}.
For example, @kbd{+L -170.000000 -85.000000 12\n} returns
@samp{Locator: AA55AA00AA00\n}.
@item l, loc2lonlat @var{Locator}
Returns @var{Longitude} and @var{Latitude} in decimal degrees at the
approximate center of the requested grid square (despite the use of
double precision variables internally, some rounding error occurs).
West longitude is expressed as a negative value. South latitude is
expressed as a negative value. Locator can be from 2 to 12 characters
in length.
For example, @kbd{+l AA55AA00AA00} returns @samp{Longitude:
-169.999983\nLatitude: -84.999991\n}.
@item D, dms2dec @var{Degrees}, @var{Minutes}, @var{Seconds}, @var{S/W}
Returns @var{Dec Degrees}, a signed floating point value.
@var{Degrees} and @var{Minutes} are integer values and @var{Seconds}
is a floating point value. @var{S/W} is a flag with @code{1}
indicating South latitude or West longitude and @code{0} North or East
(the flag is needed as computers don't recognize a signed zero even
though only the @var{Degrees} value only is typically signed in
@acronym{DMS} notation).
@item d, dec2dms @var{Dec Degrees}
Returns @var{Degrees}, @var{Minutes}, @var{Seconds}, @var{S/W}.
Values are as in @command{dms2dec} above.
@item E, dmmm2dec @var{Degrees}, @var{Dec Minutes}, @var{S/W}
Returns @var{Dec Degrees}, a signed floating point value.
@var{Degrees} is an integer value and @var{Minutes} is a floating
point value. @var{S/W} is a flag with @code{1} indicating South
latitude or West longitude and @code{0} North or East (the flag is
needed as computers don't recognize a signed zero even though only the
@var{Degrees} value only is typically signed in @acronym{DMS}
notation).
@item e, dec2dmmm @var{Dec Deg}
Returns @var{Degrees}, @var{Minutes}, @var{S/W}.
Values are as in @command{dmmm2dec} above.
@item B, qrb @var{Lon 1}, @var{Lat 1}, @var{Lon 2}, @var{Lat 2}
Returns @var{Distance} and @var{Azimuth} where @var{Distance} is in km
and @var{Azimuth} is in degrees.
All @var{Lon}/@var{Lat} values are signed floating point numbers.
@item A, a_sp2a_lp @var{Short Path Deg}
Returns @var{Long Path Deg} or @code{-RIG_EINVAL} upon input error.
Both are floating point values within the range @code{0.00} to
@var{360.00}.
@item a, d_sp2d_lp @var{Short Path km}
Returns @var{Long Path km}.
Both are floating point values.

@node rotctld protocol
@subsection @command{rotctld} protocol
@cindex @command{rotctld} protocol
@cindex protocol, @command{rotctld}
Two protocols exist for communicating with @command{rotctld}. The
``Default'' protocol is primarily used internally by Hamlib so an
application that is not written to use @command{rotctld} directly via
@acronym{TCP} network sockets can still access @command{rotctld}. The
other ``Extended Response Protocol'' is intended for the more general
use case where a variety of response formats may be needed.
@menu
* rotctld Default protocol::
* rotctld Extended Response protocol::
@end menu
@node rotctld Default protocol
@subsubsection @command{rotctld} Default protocol
@cindex @command{rotctld} Default protocol
@cindex Default protocol, @command{rotctld}
The @command{rotctld} protocol is intentionally simple. Commands are
entered on a single line with any needed values. In Perl, for exampl,
reliable results are obtained by terminating each command string with
a newline character, @samp{\n}.
@noindent
Example @code{set} (Perl code):
@example
print $socket "P 135 10\n";
print $socket "\\set_pos 135 10\n"; # escape leading '\'
@end example
@noindent
A one line response will be sent as a reply to @code{set} commands,
@samp{RPRT x\n} where @samp{x} is the Hamlib error code with @samp{0}
indicating success of the command.
@noindent
Responses from @command{rotctld} get commands are text values and
match the same tokens used in the @code{set} commands. Each value
is returned on its own line. On error the string @samp{RPRT x\n} is
returned where @samp{x} is the Hamlib error code.
@noindent
Example @code{get} (Perl code):
@example
print $socket "p\n";
"135"
"10"
@end example
@noindent
Most @code{get} functions return one to four values. A notable
exception is the @command{dump_caps} command which returns many lines
of @samp{key:value} pairs.
This protocol is primarily used by the @code{NET rotctl}
(@command{rotctl} model 2) backend which allows applications already
written for Hamlib's C @acronym{API} to take advantage of
@command{rotctld} without the need of rewriting application code. An
application's user can select rotor model 2 (@code{NET rotctl}) and then
set @option{rig_pathname} to @kbd{localhost:4533} or other network
host:port (set by the @option{-t} option above).
@node rotctld Extended Response protocol
@subsubsection @command{rotctld} Extended Response Protocol
@cindex @command{rotctld} Extended Response Protocol
@cindex Extended Response Protocol, @command{rotctld}
An EXPERIMENTAL Extended Response protocol has been introduced into
@command{rotctld} as of February 10, 2010. This protocol adds several
rules to the strings returned by @command{rotctld} and adds a rule for
the command syntax.
@enumerate
@item
The command received by @command{rotctld} is echoed with its long
command name followed by the value(s) (if any) received from the
client terminated by the specified response separator as the record
line of the response.
@item
The last line of each block is the string @samp{RPRT x\n} where
@samp{x} is the numeric return value of the Hamlib backend function
that was called by the command.
@item
Any records consisting of data values returned by the rotor backend are
prepended by a string immediately followed by a colon then a space and
then the value terminated by the response
separator. e.g. @samp{Azimuth: 90.000000\n} when the command was
prepended by @code{+}.
@item
All commands received will be acknowledged by @command{rotctld} with
lines from rules 1 and 2. Lines from rule 3 are only returned when
data values must be returned to the client.
@end enumerate
An example response to a @command{+P} command sent from the
shell prompt (note the prepended @code{+}):
@example
echo "+P 90 45" | nc -w 1 localhost 4533
set_pos: 90 45
RPRT 0
@end example
In this case the long command name and values are returned on the
first line and the second line contains the end of block marker and
the numeric rotor backend return value indicating success.
An example response to a @command{+\get_pos} query:
@example
echo "+\get_pos" | nc -w 1 localhost 4533
get_pos:
Azimuth: 90.000000
Elevation: 45.000000
RPRT 0
@end example
In this case, as no value is passed to @command{rotctld}, the first
line consists only of the long command name. The final line shows
that the command was processed successfully by the rig backend.
Invoking the Extended Response protocol requires prepending a command
with a punctuation character. As shown in the examples above,
prepending a '@code{+} character to the command results in the
responses being separated by a newline character (@samp{\n}). Any
other punctuation character recognized by the C @code{ispunct()}
function except @code{\}, @code{?}, or @code{_} will cause that
character to become the response separator and the entire response
will be on one line.
Separator character summary:
@table @code
@item +
Each record of the response is appended with a newline (@samp{\n}).
@ifhtml
@*
@end ifhtml
@item ;, |, or ,
Each record of the response is appended by the given character
resulting in entire response on one line.
Common record separators for text representations of spreadsheet data,
etc.
@item ?
Reserved for 'help' in @command{rotctl} short command.
@ifhtml
@*
@end ifhtml
@item _
Reserved for @command{\get_info} in @command{rotctl} short command.
@ifhtml
@*
@end ifhtml
@item #
Reserved for comments when reading a command file script.
@end table
Other punctuation characters have not been tested! Use at your own
risk.
For example, invoking a @command{;\get_pos} query with a leading
@code{;} returns:
@example
get_pos:;Azimuth: 90.000000;Elevation: 45.000000;RPRT 0
@end example
Or, using the vertical bar (pipe) character @code{|} returns:
@example
get_pos:|Azimuth: 90.000000|Elevation: 45.000000|RPRT 0
@end example
And a @command{\set_pos} command prepended with a @code{|} returns:
@example
set_pos: 135 22.5|RPRT 0
@end example
Such a format will allow reading a response as a single event using a
preferred response separator. Other punctuation characters have not
been tested!
All commands with the exception of @command{\set_conf} have been
tested with the Extended Response protocol and the included
@file{testrotctld.pl} script.
