Hi,
I had trouble with CTS serial port squelch (on microHAM USB Interface III).
It seems there is a bug in the hamlib code and I think the similar thing
should be done as has been done for the pttport, i.e. if the dcdport is
the same as the rigport, do not reopen it. Otherwise the serial port will
be reset to its default and it will key the radio PTT forever (because
the RTS line is reset on the port reopen). Patch attached

This flag can be used by back ends that need to take special action
while the rig is transmitting e.g. the FT-747GX and similar that do
not process CAT commands while transmitting.
The flag is also used as a default answer to rig_get_ptt if nothing
better is available.
Deal with inaccurate CAT query for Rx/Tx on the Yaesu FT-847
This rig doesn't set the Rx/Tx status flag when PTT is asserted via
the PTT pin on the rear PACKET socket so we need to override which we
can do if we known we have asserted PTT via rig_set_ptt().
Adjust style and fix set PTT defects
Fix a warning from a declaration of a deleted function definition
When the PTT serial port is not the control port the intention is to
free the port when PTT is reset so that other applications can share
it. This logic was faulty with attempts to call port functions on an
unopened port when repeatedly calling the rig_set_ptt API.
Thanks to Christoph van Wullen, DL1YCF, for finding and analyzing this
defect.
When using separate serial port for PTT via RTS pr DTR it is
convienent to close the port when the PTT line is not asserted. This
allows other applications to share the PTT serial port.
This has been achieved by ensuring that file descriptor for the port
is set to -1 when the port is closed, this then allows the invalid FD
to be used as a PTT surrogate for the rig_get_ptt API when the port is
only being used for PTT.
This change allows the set_mode functions to leave the rig passband
unchanged if required. For the few rigs that do not have explcit
passband width control either current state is read and rewritten or a
"normal" width is chosen e.g. select a normal width when there is a
choice like CW and CW-NARROW.
CAT protocols that don't allow direct addressing of VFOs require that
the "other" VFO be queried or set via a select then get/set then
select back to original or swap then get/set then swap again. When
both frequncy and mode need to be set the sequences can be optimized
if a single funciton is avaiable.
This enhancement adds those single functions rig_set_split_freq_mode()
and rig_get_split_freq_mode() with a default impelementation that
calls the individual rig_{get,set}_split_{freq,mode}() functions. Back
ends can choose to implement an optimized version which is used
instead of the default if present.
Using these functions when an optimized implementation is available
allows the TX VFO's frequency and mode to be set in a single operation
with only one VFO exchange or selection either side of the
operation. Many CAT protocols are very efficient when getting or
setting both frequency and mode and some even combine the two in a
single command.
The letters 'K' and 'k' are used for the rigctl short command name for
these functions.
The previous commit introduced a regression that masks any error
return from opening the serial port used for PTT when that port is
different from the CAT serial port.
Before this change only the line used for PTT was being lowered on
open. It is necessary for platforms other than Windows to avoid
issues with other uses of the line not used for PTT such as interfaces
that wire-or RTS and DTR together or use it for CW or FSK keying. This
is because platforms other than Windows raise both DTR and RTS on
serial port opening.
Also changed code that opens CAT port to lower RTS or DTR if it is
used for PTT. In this case there is no need to lower the other line of
DTR or RTS as there is already a config parameter to control it
(dtr_state or rts_state). This change is necessary to maintain current
functionality.
The serial port line control functions take a boolean argument not a
ptt_t argument. Changed usage in rig_open() to use a explicit zero
instead of RIG_PTT_OFF value which only coincidentally happens to be
zero.
Many APIs emulate direct VFO addressing by using caps->set_vfo() or
caps->vfo_op(..., RIG_OP_TOGGLE) to simulate direct addressing of a
non-current VFO. The mirrored function call to revert back to the
original current VFO was not checking for errors. This is not
unreasonable but it turns out that some rigs can arbitarily fail doing
VFO changes or swaps (e.g. Yaesu FT-450).
I have added checks to these calls but only fail with the error if the
API call being wrapped does not fail itself. This allows the mirroring
VFO operation to be completed, if possible, even if the wrapped
function could not be completed, hence as before, making every effort
not to change the rig state unnecessarily.
When a serial control line (DTR or RTS) is used for PTT control the
rig_open() function clears the PTT control line after opening the
port. This is necessary on Linux because opening the port sets them
both as part of the normal RS-232 protocol. The lines were not being
cleared when the PTT port was the same port as the CAT control port.
The Icom IC-7100 back end added this enum instead of using the extant
RIG_PTT_RIG enum. Also the rig_get_ptt() implementation didn't handle
it and errored out.
Note: RIG_PTT_SERIAL_CAT was added in commit
e9ee671149 - N0NB
MinGW was issuing the following warning:
CC rig.lo
rig.c: In function 'rig_init':
rig.c:330:36: warning: assignment makes integer from pointer without a cast [enabled by default]
rs->rigport.parm.cm108.ptt_bitnum = DEFAULT_CM108_PTT_BITNUM;
^
The constant DEFAULT_CM108_PTT_BITNUM was being defined as a string on
non-linux platforms. Now defined to an integer on these platforms. The
actual value may need to be corrected at some point in the future when
CM108 support is completed for those platforms.
From Martin, CT1IQI:
"Several programs under Linux rely on Hamlib for control. I wanted to
try WSJT-X (digital modes like JT65) and found that my new IC-7100 was
not yet supported, also after having compiled the current git version of
Hamlib and having compiled WSJT-X against that.
So I added a IC-7100 by taking the ic-7200 and 7420 rig files as
example, be it without going (yet) through all of the very many commands
the ic-7100 supports.
This produced the situation where there was communication, e.g. setting
and reading frequencies, but the PTT control did not work. I debugged
that to actually the lack of a PTT mode in Hamlib that uses serial and
CAT at the same time; currently PTT per 'serial' seems equivalent to
toggling certain RS232 pins but not to any serial command level. So I
added a RIG_PTT_SERIAL_CAT mode for PTT control. Now the wsjt-x program
works nicely with the ic-7100 and controls both frequency and PTT via
the single USB cable."

rig_open was giving RIG_DEBUG_ERR messsages if PTT or DCD
port was unavailable but the function was not returning an
error status.

Hi,
patch attached to enable the above which was partially coded but not
quite working.

Subject: [PATCH] Fix using same serail port for PTT and CAT
src/rig.c was coded to allow the same serial port for PTT and
CAT but them tried to open the port twice. I have added code
to share the file descriptor in this situation.

Various strncpy operations could result in a port pathname that is not a
NULL terminated string as the allowed string length is the same size as
the buffer per the strncpy manual page. This is corrected by assuring
that the allowed length is FILPATHLEN - 1.
