Dave G8KBV,
How do I make sure the TNC-Pi9k6 is recognized by the OS?? It ran successfully when I used the SD card from PiGateRMS which was also running Buster, although a different kernel version.
When I type
$ ls /dev/serial0
I get a response
/dev/serial0
What else can I try to verify that the TNC-Pi9k6 is recognized by Pi OS?
