It's left as an exercise for the reader to dissect a cable and settle the crossover/straight-through/termination questions. My eyes are too old for that kind of crap -- especially at this hour.
All one really needs to do is read the spec.

Well, Recommended Standard 232 was one of those which had much more in it than most people needed, so a lot of the pins got hijacked. It was the Standard people loved to violate. A disc drive interface is (1) less generally useful and (2) less amenable to hijacking for other purposes.
