Are any of those other pinouts "standard"?
I've found the material in
several of these Wikipedia articles to be very incomplete.
Well, for certain values of "standard", perhaps. Xylogics used one
pinout that was standard across their product line. One of the pinouts
we used is for data leads only, putting TxD, RxD and SG on pins 1, 3 and
2+6 respectively. That was devised by my boss, though I'm fairly sure
others have done the same thing. I believe some of the DB25-to-8P8C
adapters we have like that are off-the-shelf. The point of that pinout
is, of course, that you can use standard TIA-568 cables to make the
connections with Tx on one twisted pair and Rx on another, and use
standard crossover cables as a null-modem.
