The earlier note that explained the meaning of ^P to the VAX console was
correct, but there is one additional tidbit of information that VAX users
will find very useful. (It is in the manual, but the books are so big that
they only get read to answer questions; if the question does not come up...)

Background:
On the front of the cabinet is a keyswitch with five (5) positions, labelled
(on a 750): OFF, LOCAL SECURE, LOCAL, REMOTE SECURE, REMOTE. On a 780, I
beleive they are labelled: OFF, LOCAL DISABLE, LOCAL ENABLE, REMOTE DISABLE,
REMOTE ENABLE.

Data:
The difference between LOCAL and REMOTE (as you probably know) is whether
the console is the tty line from the diagnostic processor (the little 11) or
the modem on the diagnostic line.

THE USEFUL TIDBIT:----------------------------------------------------------
The difference between ENABLE and DISABLE (== the meaning of SECURE) is that
in DISABLE (SECURE) ^P is just another character. It does not switch to
"console mode".
----------------------------------------------------------------------------

I hope this helps VAX users out there by letting them remove the "hand's
off" sign from their console terminals.
