I'm trying to set up WSJT-X with my IC-7100 and I wasn't able to key the transmitter via any COM RTS/DTR line.
After an exhaustive test session that included using different software too (N1MM, MTTY, DX4WIN) here they are my findings:
1) The radio can be set up in transmission using the CAT commands, but no audio is transmitted if the PTT is not pressed (it seems remoterig DO NOT pass audio without pressing the radio PTT)
2) The radio can be keyed using COMExt only if both DTR and RTS are HIGH;
3) Using COM1 or COM2 works for sending CW (DTR), doesn't work for PTT (RTS);
Any suggestion?
