[comp.sys.apple] kermit >3.75 & vt100

Your VT100 emulator is functioning properly; it's Gnuemacs that's
not functioning properly, possibly because you haven't set up the
correct terminal handler modes.  Real VT100s do send DC3/DC1 characters
to block/unblock host transmission.

It's really much nicer if you can write a vt100 emulator that doesn't
NEED to use xon and xoff to block GnuEmacs; those keys are already
assigned in Emacs anyway, as the "quote" and "Isearch-forward" keys.
I muttered and mumbled for a long time before breaking down and giving
my terminal emulator a big (7K) received-character buffer, but there
were enough programs and systems (especially ones that were several
hops away over networks) that either wouldn't or didn't have time to
respond to xoff. It was definitely worth it.

This weekend I also finally took the time to perfect the last quirks
in my vt100 emulation; I can now proudly say it passes the vttest
program as well as the vt220 I use at work (except, of course, for the
graphics modes that my hardware doesn't have).
