Onboard Parallel Port
This option enables the parallel port on the CPC-2347 and specifies
the parallel port's base I/O address. The settings are Disabled, 378/
IRQ7, 3BC/IRQ7 and FDD. The default setting is 378/IRQ7.
The CPC-2347's floppy interface and parallel port share the same
pin assignment. When "On board Parallel port" is setting to FDD,
floppy drive will be enabled and printer port will be disabled. If
"On board Parallel port" is setting to either Disabled, 378/IRQ7 or
3BC/IRQ7, printer port will be enable but floppy drive will be
disable.
Parallel Port Mode
This option specifies the parallel port mode.
Setting Description
SPP The normal parallel port mode is used.
EPP The parallel port can be used with devices that
adhere to the Enhanced Parallel Port (EPP) specifica
tion.
EPP This uses the existing parallel port signals to provide
asymmetric bidirectional data transfer driven by the
host device.
ECP The parallel port can be used with devices that
adhere to the Extended Capabilities Port (ECP)
specification. ECP uses the DMA protocol to achieve
transfer rates of approximately 2.5 Mbs. ECP provides
symmetric bidirectional communications.
