Cyber NOS 2 AX.25 subsystem
This will come after Pi-DI, due to effort involved, and the need for Pi-DI as a prerequisite for intended testing.
This project is queued before NAM-IGCN, as an initial dive into NAM/CCP, as AX.25 is ADCCP Balanced mode compliant, a lot of code might just need modified and stripped / augmented, but not a complete from-scratch protocol like NAM-IGCN(LTP) will be. The Licklider Transport Protocol has it's own challenges on top of that. AX.25 comes first, and offers similar challenges to prepare for doing LTP
