Serial Connector
Use the 9-pin serial 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 connector.
