I have tried this also, but no difference in tcsh's behaviour.
I have even tried editing termcap.src in /usr/src/share/termcap/ and
doing a 'make install' there to see if I'm missing a step... but no luck.
I also received an off-list tip from Karl Vogel:

But neither TERMCAP nor TERMINFO are set in my normal tcsh environment.
I have tried setting and unsetting them in the order given here and
many other permutations, to no success.
I have tried logging out and back in again, in case tcsh caches termcap
somewhere that isn't updated without re-running tcsh, but I don't think
this is the case.
The only thing I haven't tried yet is rebooting - technically I don't
think I would have to.
Is there some utility somewhere that can tell me if I've got a typo in
my termcap or something which would prevent tcsh from reading my new
I suppose could write my own curses program to do this... maybe.
Is there some utility somewhere which will translate my termcap into
terminfo so I can try that? Why is there no terminfo stuff in FreeBSD 4.8?
