Hello all !
Hmh, maybe not exactly an answer but maybe a hint....!
We had this problem at our VHF-contest station.
Rig was a IC910 which automatically jumped on TX when the PTT of the
amplifier was connected to the PTT out of the IC910...!
We tested a bit and we found out that the TRX gets to PTT not only when the
input is really shorted but also when there is a resistance of aprox.
150-200 OHM !
OK this is not the COM port, but maybe it helps to look for the problem !
Jochen
PS: If I am out of order to the problem excuse these idea !
