Hello,
I have a PiGate, and the setup (TNC, Radio and cable) works well. Have made a new image now and installed YAAC. But I am not able to use the Pi9k6. I don't get any APRS messages when trying with the serial monitor. When using the pitnc_getparams I am able to read configuration from the TNC.
Tried now with a USB/RS-232 adapter and an old Kantronics KAM, and everything works.
Guess there must be a setting I have missed.
Any hints?!
