Thinking about it a little more, tput would get its notion of the
screensize from the stty-related settings first, and also could
be seeing a bogus environment variable:
If the environment variables LINES and COLUMNS are set, or if the pro-
gram is executing in a window environment, line and column information
in the environment will override information read by terminfo. This
would affect a program running in an AT&T 630 layer, for example, where
the size of a screen is changeable (see ENVIRONMENT).
A hardware vt100 wouldn't do the stuff that an operating system uses to
determine screensize, so "stty -a" (I think) would either show zeros or
would show some default value (probably just zeros).
If those look okay, then there's always running "strace" to see what
inputs tput might be getting.
