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.
Serial Port3 Address
This option specifies the base I/O port address of serial port 3. The Optimal setting is
3E8
.
Serial Port3 IRQ
This option specifies the Interrupt Request address of serial port 3. The Optimal setting is
10
.
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.
3E8/IRQ10 Set this value to allow the serial port to use 3E8 as its I/O port address and
IRQ10 for the interrupt address. This is the default setting. If the system will not
use a serial device, it is best to set this port to Disabled.
