The parallel port is PC/AT-compatible. It can operate in
enhanced parallel port (EPP) mode or extended capabilities
port (ECP) mode. The ECP mode is IEEE 1284 compliant. The
mode of operation, as well as the I/O address of the port, is
BIOS-selectable (see Appendix C for information on using the
BIOS Setup program).
