The Linux version of PB and PG talks to a pseudo TNC using the native Linux AX.25 sockets. It has been more than two decades since I have last used the native AX.25 sockets and, as far as I can remember, it was not trivial. I suggest modifying the PB and PB software to speak the AX.25 KISS over TCP protocol and talk with DireWolf, a software TNC that implements the G3RUH GFSK 9600 bps modem. DireWolf can be found here:
https://github.com/wb2osz/direwolf
I will try modifying PB and PG to use the KISS protocol as soon as I can spare some time.
DireWolf could be used with a classic transceiver via soundcard and also to a SDR receiver such as GQRX or GNURadio and a classic (or SDR) transmitter. The software modem could also be implemented directly in GNUradio as well.
It will be a blast to operate a PACSAT BBS again.

The Linux tools (PacSatTools and PB/PG) are distributed as source code. That code could potentially serve as a guide for how to encode files and interface with a KISS TNC.

Don't know if this is opensource ( a quick search only found the old
WiSP32 download setup.exe), but this as well as other old programs (I'm thinking Nova, but perhaps others?) would be best
served by getting it out there in the public domain. The other option is to reverse engineer if someone has a working copy.

For all our talented coders out there, a replacement for the venerable

software would be well received, and allow much more utilization of this satellite resource. Anyone interested?
