Onboard COM Port 1/COM Port 2
This item specifies the base I/O port address and IRQ for the onboard Serial Port
1 (LPT1B)/Serial Port 2 (JCOM1). Selecting [Auto] allows BIOS to automatically
determine the correct base I/O port address. Setting options: [Disabled], [3F8/
IRQ4], [2F8/IRQ3], [3E8/IRQ4], [2E8/IRQ3], [Auto].
UART Mode Select
This setting allows you to specify the operation mode for serial port 2. Setting
options:
IrDA, ASKIR, Normal
.
Normal
RS-232C Serial Port
IrDA

Amplitude Shift Keyed Infrared Port
RxD, TxD Active
This setting controls the receiving and transmitting speed of the IR peripheral in
use. Setting options: [Hi,Hi], [Hi,Lo], [Lo,Hi], [Lo,Lo].
IR Transmission Delay
This setting determines whether the IR transmission rate will be delayed while
converting to receiving mode. Setting options: [Disabled], [Enabled].
UR2 Duplex Mode
In an infrared port mode, this field appears. Full-duplex mode permits simulta-
neous two-direction transmission. Half-duplex mode permits transmission in
one direction only at a time. Select the value required by the IR device con-
nected to the IR port. Setting options: [Full], [Half].
