ISTR hearing mention a while back that the remote
diag console on the
6K VAXen spoke a flavor of serial DECnet. Any experience with
something like that? It would be useful, or at least interesting, to
provide a remote console for them.
The remote diag consoles spoke (I guess) plain
serial between the console and the local DEC
Remote Diagnostic Console box and some
undocumented, secret (and now probably forgotten)
protocol between the RDC and its partner unit
at the support centre.
The link between the little modem-shaped box connected to the console port
and wherever it ended up at is what I was interested in. I thought it was
just a plain old modem, but someone said (either here or on NetBSD port-
vax) that it was a flavor of DECnet. It's not quite as interesting to me
now.
As for running DDCMP over the console line, it's
probably possible but usually not a good idea
(the console line is usually deliberately pretty dumb,
the principle being that it's harder to screw up that
way).
Wouldn't try it anyway. I have enough trouble with dumb serial lines!
