max25-ctl — MAX25-Stack-Lite control (Packet Radio / AX.25, localhost)

Usage:
  max25-ctl <command> [options]

Commands:
  help              This help
  discover          List local device backends
  build             Build the project (cmake -B build && cmake --build build)
  start             Start a hardware/soft-modem path
  stop              Stop a hardware/soft-modem path
  status            Show device status
  test              Offline tests (no root)

Daemon (Linux):
  stacks/daemon/max25d   Launcher (ps shows this path, not python3)
  stacks/daemon/max25d.py   M25/1 daemon implementation
  stacks/terminal/max25-terminal   Operator UI (F10 menu, CALLERID/CALLID)

Options (start/stop/status):
  --hardware HW     modems | soft-modems
  --device DEV      max25e0 (BayCom/based) | baycom-kiss | soft-crdop

Examples:
  max25-ctl discover
  max25-ctl build
  max25-ctl start --hardware modems --device max25e0
  max25-ctl start --hardware modems --device baycom-kiss
  max25-ctl start --hardware soft-modems --device soft-crdop
  max25-ctl test

Lite scope (max25-terminal, max25d, BayCom/based, CRDOP): README.md
  SET DEVICE <id> → CONNECT → SEND via max25-terminal after max25d is up
