Piker.

The Wyse 60 -- *AND the Link MC5 *and* Adds 4000* emulations of the Wyse 60, 
which really makes you wonder how they were 'emulating' it -- would *HARD 
LOCK* if they received a... Ctrl-S (XOFF) character.

Generally, when you *send* one to a Unix box, it doesn't echo back; I don't
remember why we had it happen; 3270 emulation, I think.

But sure enough, we put some other kind of terminal in hexdump mode, and 
that's what was coming back.

And when I say hard, I mean -=*!HARD!*=-: you could not even get the terminal
into setup mode at that point, a power cycle was the only thing that would
recover it.

I would bet cash it was never fixed, anywhere ever.

Software Wyse 60 emulators (yes, I tested one, though I don't recall what)
didn't do it.  This was ca 1995 or so.
