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.
y Serial Port2 Address
This option specifies the base I/O port address and Interrupt Request address of serial port
2. The Optimal setting is 2F8/IRQ3.
Option Description
Disabled 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.
2F8/IRQ3 Set this value to allow the serial port to use 2F8 as its I/O port address and IRQ
3 for the interrupt address. This is the default setting. The majority of serial port
2 or COM2 ports on computer systems use IRQ3 and I/O Port 2F8 as the
standard setting. The most common serial device connected to this port is an
external modem. If the system will not use an external modem, set this port to
Disabled.
Note: Most internal modems require the use of the second COM port and use
3F8 as its I/O port address and IRQ 4 for its interrupt address. This requires
that the Serial Port2 Address be set to Disabled or another base I/O port
address and Interrupt Request address.
