The built-in serial por ts 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 select the serial ports’ I/O address in the Integrated
Peripherals submenu (“Super IO Device” field) of the BIOS.

One card-edge bracket, mounted with a serial por t cable, is
provided with the system board. If you want to use the secondary
serial por t, connect the serial port cable to connector J4. Make sure
the colored stripe on the ribbon cable is aligned with pin 1 of
connector J4. Mount the card-edge bracket to the system chassis.
