UART 2 Mode Controller
If you would like to set below option “UART Mode Select”, please
enable this item.
"
The choice: Enabled, Disabled.
UART Mode Select
UART Mode Select enables you to select the infrared communication
protocol—Normal, IrDA, ASKIR.
The UART mode setting depends on which type of infrared module is
used in the system. When set to “ASKIR” or “IrDA,” the UART mode is
used to support the infrared module connected on the mainboard.
"
The choice: ASKIR, IrDA, Normal.
UR2 Duplex Mode
This field is available when UART Mode Select is set to ASKIR or IrDA.
This item enables you to determine the infrared (IR) function of onboard
infrared chip.
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.
"
The choice: Full, Half.
Onboard Parallel Port
This option is used to assign the I/O address for the onboard parallel port.
"
The choice: Disabled, 378/IRQ7, 278/IRQ5, 3BC/IRQ7.
Parallel Port Mode
Enables you to set the data transfer protocol for your parallel port. There
are four options: SPP (Standard Parallel Port), EPP (Enhanced Parallel
Port), ECP (Extended Capabilities Port) and ECP+EPP.
SPP 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.
"
The choice: ECP, EPP, SPP, ECP+EPP.
ECP Mode Use DMA
When the onboard parallel port is set to ECP mode, the parallel port has
the option to use DMA “3” or DMA “1
"
The choice: 1, 3.
