The APRS/TNC speed is actually option 311, Int TNC->Data Speed, which is
1200 or 9600 only.  AFAIK, option 331 is used for peripheral devices
plugged into the USB port such as weather stations or GPS loggers.  I only
tried it here because it was only radio setting I could find that remotely
pertains to the PC serial baud rate.

FWIW, the baud detection in kenwood_live.py:get_id() indeed only tries the
baud rate there in ascending order and stops at the first successful one,
but even when I manually invert the list, 9600 is the only one detected:

That would've been my thought as well :)  I'd be happy to try out any other
tests you can think of.
