+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)
