ax25spec holds the AX.25 v2.2 specification (and the v2.3 draft) as Markdown, alongside KISS, multi-drop KISS, IL2P and the FBB forwarding protocol. ax25sdl transcribes the specification’s state-machine diagrams into data and generates the same state tables in C#, TypeScript, Go, Python, Rust, C and JSON, so every implementation built on it follows the same reading of the spec.
