- Centronics is a standard in the industry, but it is by no means "the only
- kind of port". It is a parallel.

-
- You can tell serial from parallel by the number of data pins. Parallel must
- transmit lots of info all at the same time, so it needs more pins to do this.
- Serial will usually have much fewer pins, since it is doing most of the
- transfer over one line.
