Thanks again. I can run xmodmap and xev on my laptop, but on the
university's system, I can't.
xmodmap -pk
xmodmap: unable to open display ''
and xev I can't find at all.
Sounds bad. Have you tried putting
(normal-erase-is-backspace-mode 1)
or
(normal-erase-is-backspace-mode -1)
in your .emacs? That might do what you want, or at least get you part
way there.
Although I haven't tried, I suspect that I'm not going to have much
luck getting an X session across their firewall AND mine. Is there some
other way to do this?
If `normal-erase-is-backspace-mode' doesn't do everything you need,
look at its code and see what you can do using the syntax for
remappings given there (but in your global keymap).
