I am trying to get a TNC-PI96K running with PAT to create a 9600 baud Winlink. When I first installed this I could run .pitnc_getparams and pitnc_setparams and I would get results. I turned off the Pi to try 1200baud, moved the JP1 jumper, and rebooted the Pi. Now when I try to run ./pitnc_getparams I get an error:
pi@af9w-pat:~/tnc-x $ ./pitnc_getparams 0 0
pitnc_getparams Version 0.0.0.5
Using Serial port /dev/ttyAMA0
tty_speed: tcgetattr: Inappropriate ioctl for device
Any ideas on how to get past this or even find out what the problem is? Is this the correct forum to ask?
