Creep29257/Xstatic ? reverse-engineered prompt

I want a small Meshtastic client in C that works on FreeBSD first and Linux second.

It should read a serial port, decode Meshtastic frames and protobuf data, keep track of known nodes with their names and basic info, and let me see traffic in a useful way from the command line. I need a simple CLI too, with options to list known nodes, show essential traffic, show everything, and send a text message to a node by number. Please make sure it can shut down cleanly with Ctrl C, and that sending a message actually works reliably with the firmware behavior in mind.

For now, focus on the working terminal version before any X11 window. If you need to check current Meshtastic or protobuf details, look up the latest docs online.
