I decided to program a PACTOR-IP bridge that operates in the background and independently of Pat, providing two TCP sockets for Pat—similar to how VARA works.
The PACTOR-IP bridge can, of course, also be used independently of Pat.
To achieve quick results, I also implemented a "VARA Emulation Mode," which translates WA8DED commands and responses into VARA. This allows the VARA driver already written by N8JJA to be utilized.
The whole setup is now functional. Attached are four screenshots showing the current state.
I plan to write a WA8DED driver for Pat, which can then be used directly without requiring the VARA emulation.
Stay tuned, 73s
