3BC/IRQ7
Parallel Port I/O port address is 3BC and the interrupt
address is IRQ7
Parallel Port Mode [SPP]
Use the Parallel Port Mode option to select the mode the parallel port operates in.
SPP
Standard parallel port outputs are 8-bits long. Inputs
are accomplished by reading 4 of the 8 bits on the
status register.
EPP
The parallel port operates in the enhanced parallel
port mode (EPP). The EPP mode supports
bi-directional communication between the system
and the parallel port device.
ECP
The parallel port operates in the extended
capabilities port (ECP) mode. The ECP mode
supports bi-directional communication between the
system and the parallel port device.
ECP+EPP
The parallel port operates in the extended
capabilities port (ECP) mode. The ECP mode
supports bi-directional communication between the
system and the parallel port device.
The parallel port is also compatible with EPP
devices described above
EPP Mode Select [EPP1.7]
Use the EPP Mode Select option to select the EPP mode for the parallel port. EPP1.9 is
backward compatible with EPP1.7, but some EPP1.7 devices don’t work with EPP1.9.
