OH NO!  Not "control-backslash"!  Please!

On my suns (before, sun3/160, sunos; now sparc5, solaris) that
char does NOTHING except echo.

But not KERMIT.  I dare not even try it.

At least, "control-\ C" is kermit's "get to kermit command-level"
signal-type-thing.   Maybe control-\ itself is ok with kermit.
Surely someone knows the answer.
