The parallel port can be used with devices that adhere to Standard (SPP) or Enhanced Parallel

port (EPP) specification. EPP uses the existing parallel port signals to provide asymmetric

bi-directional data transfer driven by the host device. It also can be used with devices that

adhere to the Extended Capabilities Port (ECP) specification. ECP uses the DMA protocol to

achieve data transfer rates up to 2.5 megabits per second. ECP provides symmetric bi-

directional communication. EPP + ECP is also available.

This option is only available if the setting for the Parallel Port Mode option is ECP. This

option sets the DMA channel used by the parallel port, option available are 1 or 3.
