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.
3F8/IRQ4
