UR2 Duplex Mode (Half)
This field is available when UART 2 Mode is set to either
ASKIR or IrDA. This item enables you to determine the infra-
red function of the onboard infrared chip. The options are Full
and Half (default).
Full-duplex means that you can transmit and send information
simultaneously. Half-duplex is the transmission of data in both
directions, but only one direction at a time.
Onboard Parallel Port (378/IRQ7)
This option is used to assign the I/O address and interrupt re-
quest (IRQ) for the onboard parallel port.
Parallel Port Mode (ECP)
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, a l-
lowing both data input and output. ECP and EPP modes are only
supported with EPP- and ECP-aware peripherals.
ECP Mode Use DMA (3)
When the onboard parallel port is set to ECP mode, the paral-
lel port can use DMA 3 or DMA 1.
Game Port Address (201)
This item sets the I/O address for the game port.
Midi Port Address (330)
This item sets the I/O address for the Midi function.
Midi Port IRQ (10)
This item sets the interrupt request for the Midi function.
