Yeah, COM6.? Somewhere in the Soundmodem PTT config it should also show what pin it's using on the comport, whether RTS, DTR, or both.? Here's Direwolf's PTT section, just adjust one of the lines accordingly and delete the # to enable it, or add a new line.? If the radio immediately goes into transmit when you start Direwolf, stop Direwolf and change the PTT line to what works.? I had one setup where that happened, so I had to use some variation of inverted RTS or DTR or something, but it worked.
