BIOS Setup
UART Mode Select
This field is used to select the type of IrDA standard supported by
your IrDA device. For better transmission of data, your IrDA periph-
eral device must be within a 30o angle and within a distance of 1
meter.
RxD, TxD Active
The options are Hi, Lo; Lo, Hi; Lo, Lo; and Hi, Hi.
IR Transmission Delay
If this field is Enabled, transmission of data will be slower. This is
recommended when you encounter transmission problem with your
device. The options are: Enabled and Disabled.
UR2 Duplex Mode
Half
Data is completely transmitted before receiving data.
Full
Transmits and receives data simultaneously.
Onboard Parallel Port
378/IRQ7, 3BC/IRQ7, 278/IRQ5
Selects the I/O address and
IRQ for the onboard parallel port.
Disabled
Disables the onboard parallel port.
Parallel Port Mode
The options are SPP, EPP, ECP and ECP+EPP. These apply to a
standard specification and will depend on the type and speed of
your device. Refer to your peripheral’s manual for the best option.
SPP
Allows normal speed operation but in one direction only.
“ECP (Extended Capabilities Port)”
Allows parallel port to operate in bidirectional mode and at a
speed faster than the normal mode’s data transfer rate.
“EPP (Enhanced Parallel Port)”
Allows bidirectional parallel port operation at maximum speed.
