Serial Connector

Use the 9-pin serial connector to attach a serial device to the computer. The serial connector passes data in serial format (1 bit at a time over one line). This connector 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 connector.
