terminal key mapping


I'm telneting to a Sun computer...the delete key sends ^? rather than ^h. I've tried changing my .login on the sun so that ^? is recoginzed as the erase char (stty erase ^?) but it just says no match. So, I'm trying to figure out how to remap keys from the terminal window...or figure out why the stty doesn't work (i think it is because the ? is shift-/, all other chars assigned are lowercase or non-combo keys)
