Onboard Parallel Port
This option enables the parallel port on the CPC-2245 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-2245'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. The settings are SPP,
EPP, ECP and EPP+ECP.
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) specification.
EPP 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.
