   Anyone know why #DireWolf is hellbent on using /dev/ttyS0 with hamlib? I have this in direwolf.conf, which should force it to use /dev/ttyUSB1:

   PTT RIG 1035 /dev/ttyUSB1 38400

   But it refuses:

   Dire Wolf version 1.7 Includes optional support for: gpsd hamlib cm108-ptt Reading config file direwolf.conf Audio device for both receive and transmit: plughw:0,0 (channel 0) Channel 0: 1200 baud, AFSK 1200 & 2200 Hz, A+, 44100 sample rate.

   If I make /dev/ttyS0 a symlink to /dev/ttyUSB1, it works flawlessly. What gives? :blobfoxconfused:

     @W1CDN Yep! :blobfoxthumbsup:

     I ended up fixing my issue by setting 077 FM PKT PORT SELECT to USB. :blobfox_w_antenna:

     @tk it might be a permissions issue, if the user you're running dw with isn't in the right group for the serial port?
