I used to do that for a living between 1984-1994. We had our own
board (68000, front-end application running out of local RAM,
VMS/RSTS/Unix app talking to our board to read/write/print files
to/from the bisync link). I know there were apps that supposedly ran
entirely on the VAX that used dumb sync serial cards (DUP-11, etc) but
we sold a lot of COMBOARDs to people who tried that first and gave up.
We sold HASP, 3780 and SNA products. The SNA products were a bear to
get working at different customer sites. We had a entire chapter of
docs, meant to be printed out and handed to the IBM folks, just about
how to configure the BIND. Our SNA product emulated a PU Type 2 and
let you connect from your local VT100 and appear to be a 3270 session.
It mostly worked once you got the BIND right. Bisync was a _lot_
easier to configure and get working.
