That's because the way to perform a "backspace" in such a terminal is to
send the DEL char to the application (e.g. `backspace' is bound to
term-send-backspace in term.el).

Not sure how term.el could better handle your situation.  I guess it
could try to prevent you from running the delete-backward-char command
(so at least you get to learn about the problem more directly).
or maybe it could remap delete-backward-char to term-send-backspace.
