"""
HyBBX-ready check - must use same open port as boot-wait (DTR must stay high).
After boot-wait closes the port, DTR drops and the TNC often returns to echo mode.
Use: ./tnc2c-boot-wait.sh (includes HyBBX verify by default)
Or: ./tnc2c-integration-test.sh --boot (boot-wait + verify in one process)
