Normally, serial ports come in 9 or 25-pin varieties. Most PCs built

No they're not, they're MALE. You *do* know the difference, don't you?!


Printer ports are not serial ports, as a rule. 15-pin is also pretty
odd - printer ports are normally 25-way male.

WRONG again - they're FEMALE. Have a look at the back of your PC!

A serial cable needs to have a female plug to connect to the male port.
Similarly, a parallel cable needs a male plug to connect to the female port.
