This isn't what the previous poster was talking about. This case is fairly
easy to do. I'd be *REAL* interested to see a 3270 looking like a glass 
tty. It's easy enough to do for line-at-a-time operation, but when you're
looking for each character individually (like in vi) the poll delay,
host interrupt rate, and bandwidth restrictions will kill you quick.
Not to mention being forced to hit one of the "transmit" keys in
addition to the keystroke you wanted (like "enter" or "PA1" or ...).

If you folks find something that comes close, *PLEASE* let me know.
We've struggled long and hard to make our Unix (tm AT&T) accessible
to users with 3270 terminals. We've succeeded in most areas, but 
editors (for example) we've had to provide parallel solutions for.

Interesting side note: "rn" (the news reading tool) is written for
glass tty but runs OK on 3270 in our system - just to show that
there are SOME applications that expect individual characters that
work on 3270.

Let me know if I can clarify this any more.

I'll tell you when I'm giving you the party line. The rest of the time
it's my very own ravings (accept no substitutes).
