The following was originally posted to net.misc .  I now know
it should have gone to met.dcom .  Sorry.

Does anyone know why a noisy line on a 212A data
connection results in one or the other end seeing
the RUBOUT or DELETE (127, 0177, Hex-EF) or the left
brace (123, 0173, Hex-EC)?

I've also seen the tilde (126, 0176, Hex-EE) followed by
the lower case 'r' as well.  At work I had "~r" a lot.
Lately at home I get the RUBOUT (which creates havoc with
my editing and will soon drive me to suicide!).

There are other problems I run into as well with
the 212A (official Bell version).  Occassionally
I make a connection and the "MC" lamp on the data
set doesn't go out and I can't send or receive over
the connection although the connection does stay up.
Both 212A's were supposed to be in factory configuration
although I didn't verify this myself.  I suspect this
is a "level" problem.  People close to the destination seem
to be able to work with these modems.
