Likely interesting readings from 1981 (and 1985) are:

( ok, I looked for a) old documents, b) containing word VAX )

For 4.1BSD the BBN code was the thing (entry BBN-VAX-UNIX(*)),
for 4.2BSD the Berkeley team did a lot of work, but per
the entry BERKELEY-VAX-UNIX-4.2(*) they apparently just
pulled in BBN code and made some small changes.

(*) At the tcp-ip-implementations.txt.1

So, instead of Berkeley Socket API, perhaps we should
refer to "BBN Socket API" ?

Also, very likely that BBN code is the source of the
TCP URG one-off processing error in 4.* BSD systems,
and their derivatives ?
