A good move.

There is a terrifically easy way to do this, and it doesn't involve any
socket work. What you need to do is write a program that reads the KISS
data file and writes the data to a terminal. This program should then
transmit its data to one end of pseudo-tty with the other end of the
pseudo-tty connected to the kernel code with either axattach or kissattach
depending on the version.
This would exactly emulate the way that the data would be received on a
KISS TNC and you would be able to monitor the received data with the
listen utility and even with another copy of xpb running. All you need to
do is master tty programming. It may pay you to look at the program mkiss
in the ax25-utils as that writes to a terminal and makes use of some of
the helper functions that are in libax25.

It certainly is.
