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 IrDA-compliant Serial Infrared Port
ASKIR 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
This setting controls the operating mode of IR transmission/reception. Setting
options: [Full], [Half]. Under [Full] Duplex mode, synchronous, bi-directional trans-
mission/reception is allowed. Under [Half] Duplex mode, only asynchronous, bi-
directional transmission/reception is allowed.
Use IR Pins
Consult your IR peripheral documentation to select the correct setting of the TxD
and RxD signals.
Parallel Port
There is a built-in parallel port on the on-board Super I/O chipset that provides
Standard, ECP, and EPP features. It has the following options:
[Disabled]
[3BC/IRQ7]
[278/IRQ5]
[378/IRQ7]
Parallel Port M ode
This field selects the operation mode for the onboard parallel port. Setting options:
[SPP]
[EPP]
[ECP]
[ECP + EPP]
[Normal]
EPP M ode Select
The onboard parallel port is EPP Spec. compliant, so after the user chooses the
onboard parallel port with the EPP function, the following message will be dis-
played on the screen: "EPP Mode Select." At this time either [EPP 1.7] spec or
[EPP 1.9] spec can be chosen.
ECP Mode Use DMA
The ECP mode has to use the DMA channel, so choose the onboard parallel port
with the ECP feature. After selecting it, the following message will appear: "ECP
Mode Use DMA." At this time, the user can choose between DMA channel [3] or
[1].
