More information:

changing the baud rate does make a difference. If I set the baud rate to 
9600, then:

IC735 : radio follows band changes 90% of the time. Correct frequency is
displayed after the band change. Lots of "# Radio one communication
error". However, TR does not detect band/frequency the radio is on when
starting the program, and the frequency is never displayed. Changing bands
from the radio is not picked up by the program.

IC781, 761 : do not function at all at 9600 baud

OMNI6 : like IC735, but no communcation warnings displayed.
