Rex,
just an FYI the older original serial ports were also 25pin D-SUB connectors?
on the rear of the PC, the main physical difference was the PP had?
holes(female) and the serial had pins(male).

The 25 pin port is the parallel port, the one you want. The serial port is?
a much smaller port/connector.
With a serial port, all the data goes over one pin/wire in serial fashion.?
With a parallel, each bit has it¡¯s own pin/wire and all the bits in each?
byte go over together (in parallel). That¡¯s why it requires more pins.
