You didn't mention what TNC you are using. Also, whether you have the
TNC already in kiss mode or use a script to bring it into kiss mode.

I use simple script to assign the ports\addresses and at the top it puts
the TNC into kiss mode.

Something like this:

# ! /bin/bash
#
# Firmware-TNC's placed into kiss mode
stty 9600 < /dev/ttyS0
echo -e "r\kissrestart\r" > /dev/ttyS0
# sleep 3
