Serial Port2 Address
The base I/O port address and Interrupt Request address of serial port 2. The Opti-
mal setting is 2F8/IRQ3.
Serial Port3 Address
The base I/O port address of serial port 3. The Optimal setting is 3E8.
Remarks: It is recommended not to change this address since Touch uses the
address of COM3.
Serial Port3 IRQ
The Interrupt Request address of serial port 3. The Optimal setting is 10.
Serial Port4 Address
The base I/O port address of serial port 4. The Optimal setting is 2E8.
Serial Port4 IRQ
The Interrupt Request address of serial port 4. The Optimal setting is 11.
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 physi-
cally 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 set-
ting. The majority of serial port 2 or COM2 ports on computer sys-
tems 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.
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 physi-
cally 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 set-
ting. If the system will not use a serial device, it is best to set this port
to Disabled.
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 physi-
cally becomes unavailable.
2E8/IRQ11 Set this value to allow the serial port to use 2E8 as its I/O port
address and IRQ11 for the interrupt address. This is the default set-
ting. If the system will not use a serial device, it is best to set this port
to Disabled.
