2.7.1 Serial Ports
The built-in serial ports are RS-232C asynchronous communication ports with 16C550A-compatible UARTs that can be used with modems, serial printers, remote display terminals, and other serial devices. You can set the serial ports’ I/O address in the Integrated Peripherals setup of the Award BIOS.
Connecting the Serial Ports
Two serial port cables mounted on a card-edge bracket are provided with the system board. Connect one serial port cable to connector JP4 for COM 1 primary serial port and the other serial port cable to connector JP3 for the COM 2 secondary serial port. Make sure the colored stripes on the ribbon cables are aligned with pins 1 of connectors JP3 and JP4. Mount the card-edge bracket to the system chassis.
