2.7.2 Serial Ports

COM 1
Serial Port
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 select the serial ports’ I/O address in the Integrated
Peripherals submenu (“Onboard Super IO Device” field) of the
BIOS.
Connecting the Serial Ports
The system board is equipped with an onboard serial por t (CN6 -
Teal/Turquoise) for COM 1 primar y serial por t. It is also equipped
with a 9-pin connector at location J17 for COM 2 secondary serial
port.
One card-edge bracket, mounted with a serial port cable, is
provided with the system board. If you want to use the secondary
serial port, connect the serial port cable to connector J17. Make sure
the colored stripe on the ribbon cable is aligned with pin 1 of
connector J17. Mount the card-edge bracket to the system chassis.
