The 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.
The system board is equipped with an onboard serial port (CN4 -
Teal/Turquoise) for COM 1 and a 9-pin connector at location J7 for
COM 2.
One card-edge bracket, mounted with a serial port cable, will be
provided as an option. If you want to use the COM 2 serial port,
connect the serial port cable to connector J7. Make sure the colored
stripe on the ribbon cable is aligned with pin 1 of connector J7.
Mount the card-edge bracket to the system chassis.
BIOS Setting
Select the serial ports’ I/O address in the Integrated Peripherals
submenu (“Super IO Device” section) of the BIOS. Refer to chapter
3 for more information.
