Are you using ttyUSB1 for anything other than PTT?

If you have ttyUSB1 set to hardware flow control, that may cause problems.
I think you can do this with the stty app.
You can check the settings with
?? stty -a -F /dev/ttyUSB1?
and change the hardware flow control with
? stty -crtscts -F /dev/ttyUSB1
This will ensure flow control is disabled for that port, and free up the pin for Direwolf to use.

Hopefully it is that simple!

The only thing that should be using ttyUSB1 or 0 is whatever ham software I am running at the time. They are virtual ports generated by having the 991a plugged in to the USB port.
Thanks
