[Info-vax] VMS terminal support

[JF Mezei]

USB eliminated the terminal / modem (DTE-DCE IRRC) confusion about
pinouts and cross overs by formalising and limiting USB to a
master/slave architecrture with different plugs for each.

But that means you can't get a camera to talk to a phone because both
are defined as slaves.

Ethernet had that problem too, but now, many ethernet chips automaticaly
adapt and the need for crossover cables is less.

Being francophone with a ç in my name, I always set serial equipment to
8 bits no parity. There were times when some equipment was configured to
7 bits with some parity and that caused me problems.

It was easy to test though. Typing an é on a non 8 bt line would cause
its high order bit to be chopped off and the character would come back
as an i.

If serial had evolved instead of being abandonned I suspect you'd see
most of its intricacies removed with more automated adapattion by the
serial chips.
