>The amount of needed detail on getting a RS-232 wired correctly...

Hah!

I can remember when there was no one way to wire an RS-232C connection correctly, what with interfaces needing null modems or not, different forms of hardware handshake, and other oddities. An essential bit of kit was a "breakout box" which had LEDs letting you see which signals each end was sending, plus little switches so you could try various guesses as to what signals it might be expecting.

The young kids these days, they have it so easy. :)

I remember breakout boxes - don't know at the moment where mine has got itself to, but I do know where the half-dozen different serial cables and gender changers I have are.

As an aside - I wonder how many readers here think "gender changers" is something to snicker at, not an extremely useful tool?

I'll be off to order my copy now. Thanks Jon!
