I think that is correct, with an Icom radio you will need a CI-V interface.

Or you could look at using VOX to key the radio.

I thought this was the only radio hookup I was getting successful PTT operation with (using fldigi and flrig, according to the setup directions for the 7100), but using the same setup for AGWPE, I can hear packets just fine (better than with the hardware TNC I have connected to another radio), but I can't get the 7100's transmitter to key up (even though AGWPE blinks the task bar lights to indicate it is transmitting).
> I'm using COM9 as the serial port (the first serial port on the IC-7100's USB connection), and Sound Card as the TNC type through the 7100's USB audio device. I know I'm hooked up to the right audio device because I am successfully decoding received packets. But it won't key the transmitter.
