UART Mode Select (Normal)
This field is available if the Onboard Serial Port 2 field is set to
any option but Disabled. UART Mode Select enables you to
select the infrared communication protocol: Normal (default),
IrDA, or ASKIR. IrDA is an infrared communication protocol
with a maximum baud rate up to 115.2K bps. ASKIR is Shar-
p's infrared communication protocol with a maximum baud
rate up to 57.6K bps.
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, al-
lowing both data input and output. ECP and EPP modes are only
supported with EPP- and ECP-aware peripherals.
