Mode
This field allows the user to select the parallel port mode.
In addition to “Output only” and “Bi-directional”, there are two faster bidirectional
modes available - the ECP (Extended Capabilities Port) and EPP (Enhanced
Parallel Port) modes.
ECP uses the DMA protocol to achieve data transfer rates of up to 2.5 Mb/s and
provides symmetric bidirectional communication. On the other hand, EPP uses
existing parallel port signals to provide asymmetric bidirectional communication.
