Summary: Racal-Vadic 1200 baud protocol

One interesting point:  I used to use a dumb terminal at home with
a RV 3451 modem at 1200 baud.  The VAX answering the phone call also
had RV modems, so they were using the RV 1200 baud protocol between them.
Everything was perfect for 3 years - rareley (if ever) did I ever see
any phone noise on the lines.

Then recently I switched to an AT&T 3b1 (the UNIX PC) with an internal 1200
baud Bell modem.  Now on almost every call I see the spurious characters
(usually the "{" and "i" characters), sometimes a few per call,
sometimes a few per minute.
