Description
Set this value to prevent the serial port from accessing any system
resources. When this option is set to Disabled, the serial port
physically becomes unavailable.
Set this value to allow the serial port to use 3F8 as its I/O port
address and IRQ 4 for the interrupt address. This is the default setting.
The majority of serial port 1 or COM1 ports on computer systems use
IRQ4 and I/O Port 3F8 as the standard setting. The most common
serial device connected to this port is a mouse. If the system will not
use a serial device, it is best to set this port to Disabled.

address and IRQ 3 for the interrupt address. If the system will not use
