The system board is equipped with 3 onboard serial ports at
locations CN4 (COM 1 and COM 2) and CN6 (COM 4). These
serial ports are RS-232 and/or RS-485 asynchronous communication
ports with 16C550A-compatible UARTs that can be used with
modems, serial printers, remote display terminals, and other serial
devices.
Jumper Setting
If the serial device connected to COM 4 requires auxiliary power
from the system board, set JP1 appropriately. Refer to “COM 4
RS232/RS485/AUX Select” in this chapter for more information.
BIOS Setting
Select the serial ports’ I/O address in the Integrated Peripherals
submenu (“Super IO Device” section) of the BIOS. Refer to chapter
