GS-232B: Fix frequent hangs because of wrong end of line

From Paul:
" ...   I am using the Win32 hamlib program, rotctl.exe
version 1.2.15.1 with a Yaesu GS-232B antenna rotator controller interface
device.  Rotctl.exe is not operating as expected however.  It frequently
hangs on some of the commands.  I have successfully commanded the
controller using a dumb terminal and I have watched the characters that are
sent with a scope.  It appears that the hamlib rotctl.exe is sending
incorrect line termination characters when sending out commands.  It should
send carriage return only ("\r") and not carriage return and line feed
("\r\n") as it is currently doing.

I have attached page 15 from the user manual for the Yaesu GS-232B
controller interface device (also found at
http://gatorradio.org/Manuals/Yaesu_GS-232B_Manual.pdf) which shows the
proper line terminators."
