Works fine. I'm not sure that I understand the GPIO terminology or if the GUI needs an update. I was designating the physical pin and it turns out that it is the GPIO Port number (GPIO 25 on pin 22). The other thing I ended up doing was editing the .ini file with Nano to configure the KISS port. That could have just been me being impatient with the GUI. With that out of the way, it worked well with piLinBPQ in place of Direwolf which is what I was after.

John, thanks for the quick response. I'm moving forward.
