I'm thinking in this case there was "industry practice." There were
other competing standards/conventions, and maybe whoever was asked or
decided to try to formalize whatever-the-Bell-DataSet is doing, perhaps
there were draft revisions of that for a while. Or they just didn't make
wide distribution, since there wasn't much need yet (early 60's few people
still had computers, let alone two of them to talk to each other over a
modem -- story was different towards the end of the 60's).

Of course, the question comes up. Which came first?
RS-232 or industry
practice?
This question is asked not infrequently in ANSI standards development.
Do we take something already in existence and slap a "standard" label on
it or do we invent something completely different?
