"Pricey" doesn't cut the mustard, I'm afraid!
But it's an interesting topic, surely? Almost every bit of kit has some sort of serial connector on the back, does it not? Back in my younger (and, it must be said, more
enthusiastic) days, I used to collect all those pin-outs in a notebook (long lost now, sadly).
You could, for instance, often check the voltage of batteries (
eg, on infusion pumps) without opening up the unit concerned.
Perhaps I'll get around to making up a universal data capturing kit one of these fine days. You never know.
