You have been misusing the D-sub connector terminology

No I haven’t and the same is true for approximately everyone else.

Because we have not been using D-sub connector terminology at all. We have been talking about the things that come with (and without) DB9 connectors. We have been (mostly) playing —- as the witty Wittgenstein would say — a different language game.

That’s why you know what I mean. So bring me a slab.
