I think you need another program to make this work. It intercepts the serial port for the FSK/PTT and makes it all work together.
I use 2-Tone instead of myth and seem to get by with just it and n1mm. For interface I use my WINKEYER-USB with the latest firmware. I use a “Y” adapter in the KEY line. The second line goes to K3/Acc2 FSK pin. “Diddles” go to FSK and “Dit-Dahs” go to CW. works well.
