Normal
The normal parallel port mode is used.
Bi-Dir
Supports bidirectional transfers on the parallel port.
EPP
The parallel port can be used with devices that adhere to the Enhanced
Parallel Port (EPP) specification. EPP uses the existing parallel port signals
to provide asymmetric bidirectional data transfer driven by the host device.
ECP
The parallel port can be used with devices that adhere to the Extended
Capabilities Port (ECP) specification. ECP uses the DMA protocol to
achieve transfer rates of approximately 2.5 Mbs. ECP provides symmetric
bidirectional communications.
Parallel Port DMA
#"
This option is only available if the setting for the Parallel Port Mode option is
ECP. The settings are Disabled, DMA CH (channel) 0, DMA CH 1, or DMA CH 3.
The default setting is Disabled.
