UART 2 Mode Default: Standard

This field is available if the Onboard Serial Port 2 field is set to any op-

tion but Disabled. UART Mode Select enables you to select the infrared

communication protocol—Standard (default), HPSIR or ASKIR. HPSIR

is Hewlett Packard’s infrared communication protocol with a maximum

baud rate up to 115.2K bps. ASKIR is Sharp’s infrared communication

protocol with a maximum baud rate up to 57.6K bps.

The UART mode setting depends on which type of infrared module is

used in the system. When set to ASKIR or HPSIR, the UART 2 is used

to support the infrared module connected on the mainboard. If this op-

tion is not set to Standard, a device connected to the COM2 port will no

longer work.

IR Function Duplex Default: Half

This field is available when UART 2 Mode is set to either ASKIR or

HPSIR. This item enables you to determine the infrared (IR) function of

the onboard infrared chip. The options are Full and Half (default).

Full-duplex means that you can transmit and send information simulta-

neously. Half-duplex is the transmission of data in both directions, but

only one direction at a time.

TX,RX inverting enable Default: No, Yes

Defines the voltage level for Infrared module RxD (receive) mode and

TxD (transmit) mode. This setting has to match the requirements of the

infrared module used in the system.

Onboard Parallel Port Default: 378/IRQ7

This option is used to assign the I/O address for the onboard parallel

port.

Onboard Parallel Port Mode Default: ECP

Enables you to set the data transfer protocol for your parallel port. The-

re are four options: Normal (Standard Parallel Port), EPP (Enhanced

Parallel Port), ECP (Extended Capabilities Port) and ECP+EPP.

Normal allows data output only. Extended Capabilities Port (ECP) and

Enhanced Parallel Port (EPP) are bi-directional modes, allowing both

data input and output. ECP and EPP modes are only supported with

EPP and ECP aware peripherals.
