PARALLEL PORT

The PCI-934 provides a bi-directional parallel port, compatible with PC/XT, AT, PS/2,
EPP and ECP modes.
To operate in EPP or ECP mode, the peripheral must be designed to operate in this mode
and the BIOS setup must be configured to support it. The differences between the three
modes appear in their pin assignation.
