Serial Line Control Test Failure Information

Test Group 4502

Device Serial Ports

This group tests serial ports. A serial port (sometimes called a COM port) is a physical interface through which information transfers in or out one bit at a time according to the RS-232 standard. Tests are provided to verify the functionality of the serial ports as they transmit data and receive data, manipulate various control signals or set different transmission (baud) rates.

Each device identified by this group is a serial port.

Note: Serial port hardware is available in almost every PC system, but external connections are often missing. Similarly, multi-port extender cards may feature internal headers for additional backplates that may not be installed. It is not possible for software to detect if ports have external connections.
