The IrDA is Hewlett Packard infrared communication protocol with maximum baud
rate up to 115.2K bps, and the ASKIR is Sharp infrared communication protocol
with maximum baud rate up to 57.6K bps. The UART2 Mode Setting depends on
which type of infrared module is used in the system. When set to "ASKIR" or "IrDA",
the UART2 is used to support the infrared module connected on the motherboard.
If this option is not set to "Normal", a device connected to the COM2 port will no
longer work.
RxD, TxD Active. It will define voltage level to match for your infrared module used
in the system.
IR Transmission Delay. When set to "Enabled", you will utilize, the capability of
your motherboard to allow for faster infrared transmission rates.
The available options for UART2 Mode Select are : [Normal] [IrDA] [ASKIR].
The available options for RxD, TxD Active are : [Hi,Lo] [Lo,Hi] [Lo,Lo] [Hi, Hi].
The available options for IR Transmission Delay are : [Enabled] [Disabled].
The available options for UR2 Duplex Mode are : [Full] [Half].
The available options for Use IR Pins are : [IR-Rx2Tx2] [RxD2,TxD2].
6.4.9 Onboard Parallel Port
This item controls the onboard parallel port address and Interrupt.
The available options for Onboard Parallel Port are : [378/IRQ7] [278/IRQ5] [3BC/
IRQ7] [Disabled].
6.4.10 Parallel Port Mode
EPP Mode Select
ECP Mode Use DMA
These item lets you set the parallel port mode.
[SPP] : Standard Parallel Port is the IBM AT and PS/2 compatible mode.
l
[EPP] : Enhanced Parallel Port is enhances the parallel port throughput by di-
l
rectly writing/reading data to/from parallel port without latch.
[ECP] : Extended Parallel Port is supports DMA and RLE (Run Length Encoded)
l
compression and decompression.
EPP Mode Select item lets you select EPP version to match your parallel device.
ECP Mode Use DMA item lets you set the DMA channel of ECP mode.
The available options for Parallel Port Mode are : [SPP] [EPP ] [ECP] [ECP+EPP].
