The baud rate is fixed in the app_rpt s/w.

The problem is very likely to be in the interface. What are you using
for an interface? Note the interface is not the usb to serial converter,
and it is not the pre-made up Kenwood serial cable either. It is usually
a homebrew circuit which merges the output from the sound fob and the
serial port together, oh, and it requires power from the modified FOB as
well.

Please refer to the interface circuit here:
