Joe,
the RTS pins of the Radio 1 and Radio 2 COM ports can be (permanently) 
set high or low  (menu "Rotor Setup"). I added that option several years 
ago to have a source for feeding CAT interfaces. Also, the RTS pin of 
the  Radio 1 COM port must be set high if the radio is a TS-2000. This 
became necessary when I replaced (with V. 12.8c) the old MSComm32 
component (which supports  only 16  port numbers) by a newer one that 
can handle more ports.

The DTR pins of  the Radio 1 and Radio 2 COM ports can also feed 
interfaces.  The Radio 2 DTR pin can alternatively (menu "Options") be 
used to automatically steer an antenna switch  (or cross switch for 2 
antennas and 2 radios) when the user switches between uv and vu sats or 
vice versa.  The feature requires different uplink/downlink patterns but 
doesn't work on the base of a particular satellite name (but see below).

The program's "Priority" feature can be used to automatically switch the 
program to a particular satellite when it rises. The antenna could then 
be switched manually (not too much work, I think).

Provided you run 2 radios (to activate the Radio 2 functions) you could 
theoretically have a group that contains your particular satellite and 
only others with a reverse uplink/downlink pattern. Then the program 
could automatically switch to your  satellite when it rises and also 
switch the antennas. (I hope, hi, I didn't test that) .
