What is cyISPortSigCD?
This read-only enumerated value reports the current state of the CD/DCD (Carrier Detect) signal on a serial port as down(0) or up(1). An admin checks this signal to confirm the serial link to the connected device is physically active, since a down state can indicate a disconnected cable. A value of down(0) on a port that should be connected suggests a cable issue or that the far-end device is powered off.
