I have verified that the TNC is active on the serial port by using

Note that Minicom has special privileges assigned to the binary on
some installs. Even if it doesn't it's probably set to the correct
group for access to your serial port. Check the permissions on your
serial port or your USB->Serial adapter:
$ ls -l /dev/ttyS0
crw-rw---- 1 root dialout 4, 64 Feb 14 09:12 ttyS0
So my serial port is read/writable by the dialout group (the second
set of "rw" applies to the group). I don't have a USB->Serial cable
plugged in right now, but I think that usually comes in as "/dev/USB0"
or similar. You can look at that device as well with "ls -l". Try "ls
-l USB*".
After you figure out which group the ports are in, use your admin
tools to add your login to that group, or edit /etc/group directly and
add your name to the end of that line. Here's a typical entry in
/etc/group:
dialout:x:16:username
Change "username" to your login. Then log out and back in again (no
need to reboot) and you should gain the "dialout" group privileges.
