Description: The state of DCD signal.
What is cyISPortSigCD?
This object reports the current state, down(0) or up(1), of the DCD (Data Carrier Detect) hardware signal line on this serial port. Admins check this to see whether the connected device is signaling an active carrier/connection on the line, useful for modem or similar serial connections. A state of up(1) confirms the connected device is asserting carrier detect, indicating an active physical connection.
