Maybe this will give you an idea of what we need - it's the wall command on my node (Daria's code, not mine, but I run it).

Now obviously, it handles the user input as well as the data, but it gives you an idea of how simple this can/needs to be:
https://github.com/juniberry/NodeWall/blob/main/wall.py

What happens is you connect to my node, and issue the wall command, and my node telnets to localhost invoking this script via a systemd socket daemon, and just passes the I/O back and forth to the node's AX.25 stack.
