A better answer:

In the shell, type

    stty erase ^H

It will make sure ^H actually is the erase (backspace) character.

Thanks.  I told you it was stupid.  But not as stupid as it sounds.  I had tried
stty -a to find out what the erase character was (reported ^?), and had tried
typing that as my backspace, but it didn't work.

Oh well, stty erase ^H does work.

Thanks again,
Rob
