I've never seen those messages before, but they suggest that you've
removed the cons25w entry (the one above cons25). ``tc=cons25w''
means, effectively, set everything else to be the same as cons25w.
As others have pointed out, termcap is very sensitive to trailing
whitespace.
I've sent you my termcap file in a private e-mail. That definitely
works, see what you get with it (you'll need to run cap_mkdb on it).
You should see ``mode file ....'' at the end of the SYNOPSIS line in
the chmod manpage in yellow.

If I buy a copy of WinDelete, and it doesn't delete Windows,
am I entitled to my money back?
