IR Function Duplex: 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. Full-duplex
lets you transmit and send information simultaneously while half-
duplex (default) is the transmission of data in both directions, but
only one direction at a time.
TX, RX inverting enable: Defines the voltage level for Infrared
module RX (receive) mode and TX (transmit) mode. This setting has
to match the requirements of the infrared module used in the system.
The options are:

ECP Mode Use DMA: When the onboard parallel port is set to ECP
mode, the parallel port has the option to use DMA 3 (default) or
DMA 1.
Parallel Port EPP Type: Sets the EPP specification. There are two
options—EPP1.9 (default) and EPP1.7.
