1.2.6 Parallel Port
The parallel port allows the attachment of devices that accept eight bits
of parallel data at standard transistor-transistor logic (TTL) levels.
The port has a 25-pin, D-shell connector and is designed primarily for
printers. However, the port can be used as an input/output port for any
device or application that matches the input/output capabilities of the
port. When adapters with additional parallel ports are installed, the
system can support three devices, each addressed separately as PARALLEL 1,
PARALLEL 2, or PARALLEL 3.
Note: Conflicts occur when using multiple devices if two or more devices
are addressed the same. Select the Set configuration option from
the system programs on the hard disk drive. Select View
configuration to verify that no lines are addressed the same.
