^Y Trapping (with apologies to UNIX hackers)
>From Harvard@CMU-10A Fri Jan 22 12:44:28 1982
       I distinctly remember writing a 20-line VAX MACRO
program (though I could have done it just as easily in
FORTRAN) that ASTed on every character, and exited when
^E was typed.  ^Y's acted like normal characters -- I
can't remember the exact syntax for image-mode I/O,
but I would be happy to look it up for you if you'd
like, and I could even get someone back at AFWL
to FTP the source to me.  (You know, of course, that
$ ON CONTROL_Y THEN ... is the painless way of trapping ^Y's
in com files; I'm describing a more general method.)
       The only problem with image mode is that you
have to do EVERYTHING, including echoing, rubout
processing, and so forth.  Note that unless you write
a routine to implement ^S/^Q handling (not very hard
to do), image mode is not likely to work very well
at 9600 baud on VT100's/DT80's.
               Regards,
               RMC
