I don't think this is right.  I thought that the Control-A was the *only*
control character Kermit would use.  Further, I thought Kermit was designed
for use in a hostile environment, i.e., one where characters coming from
the serial line were seven bits long, and where control codes such as
X-ON, X-OFF and del did nasty things.

As for a good escape sequence, I am partial to the one used on our AT&T
ISN.  / BREAK.  I believe that the BREAK has to be typed within a second or
so after the /.  This escape sequence seems to be transparent to all the
software we have tried.
