Serial Port Connector
Use the 9-pin serial port connector to attach a serial device to the computer. The serial port passes data in serial format (1 bit at a time over one line). This port
supports a variety of devices, including a serial mouse, that require serial data transmission. If you reconfigure your hardware, you may need pin number and signal
information for the serial port connector.
