I checked, TERMCAP isn't even set on any of my logins. Nor are there any
other variables in my shell's 'set' or 'setenv' listings that resembles a
termcap entry, in fact nothing is longer than PATH/path, which is still only 2

One of the failing machines:
LIGHT% ident /usr/share/misc/termcap
$NetBSD: termcap.src,v 1.59 2000/04/29 02:49:39 mycroft Exp $
And since TERMCAP isn't set, unsetting TERMCAP doesn't do anything.

Well it was definitely a change for the worse for everybody who
connects to my machines, more users have started to complain. I left the
rest of v1.59 intact but changed xterm-xf86-v33 back to xterm-r6 and all
of my machines/users are happy again.
Thanks for the suggestions, the TERMCAP variable does not seem to
have any effect on the problems I'm having, changing the one line in
termcap.src is the only thing so far that seems to fix it. I tried just
setting TERM settings manually and verified that xterm-xf86-v32 seems to be
where the real problem is (not too surprising since xterm and xterm-xf86-v33
add very little to v32, but even if I set the TERM variable to v32 things
go back to the failing state. I really think things must be hosed in this
