I am not sure that I understand the problem. Surely you *want* the
previous character to be erased when you press the backspace key?
But perhaps your problem is similar to the one I had, in which case I
My problem was that DEL (^?) from my keyboard (actually from the OS's
console driver) was getting mapped to BS (^H) by "screen", so I had no
way of sending DEL (^?) to applications behind "screen".
It turned out that screen's built-in configuration includes
keymap -d -k kb ^H
which means "when you see the string described by the termcap 'kb'
capability, map it to ^H". ('kb' is what the terminal sends when the
user presses the backspace key, and ^H is what screen thinks it should
send to emulate a vt100's backspace key.) My console was pcvt on the
i386 platform, and I was using TERM=pcvt25. The pcvt25 termcap entry,
in common with many termcap entries, has 'kb=\177' (\177 is the same as
DEL or ^?). So screen was mapping DEL to BS.
The fix I adopted was to add
keymap -d -k kb
to my .screenrc file. This cancels the built-in mapping, and allows DEL
(^?) to get from my keyboard to the application without being molested by
