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 a general input/output port
for any device or application that matches its input/output capabilities.
The connected device is identified (addressed) by system configuration as
Parallel 1, Parallel 2, or Parallel 3.
