Serial Port

COM 2

Serial Port

The system board is equipped with onboard serial ports (COM 1:

CN3 and COM 2: CN5) - both in Teal/Turquoise color located at

the ATX double deck ports of the board.

These 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

submenu of the BIOS.
