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.

setting is 7.
Option
Description
5
This option allows the serial port to use Interrupt 5.

majority of parallel ports on computer systems use IRQ7 and I/O Port 378H as the
standard setting.
Parallel Port DMA Channel :
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
