Also, beware of male vs. female DB-25 connectors.  I was once confused
reading a supply catalog until I figured out that a genuing "male"
DB-25 *does* *not* have pins in it!  The one with pins is "female".
Apparently, it's not the gender of the little pins that counts, but
rather the gender of the outermost metal shell around the insulator
that separates all the bins/sockets.  On a "male", the outermost metal
shell is recessed relative to the insulator.

Or am I totally confused?
