Getting backspace to work with RXVT/Eterm/konsole/etc

Hi there,

I'm having difficulty getting cone to detect my backspace key.  Has anyone
managed to get cone to work with a term such as RXVT or Eterm without
changing the behavior of the backspace to emit '^H'?

My backspace key currently emits '^?' which is correct, but only hitting
ctrl-H in cone seems to delete backwards.

In rxvt, I have the TERM variable set to "rxvt", and I have this in my termcap
database.  I've tried changing it to "ansi" and things, but with no effect.  
All other apps I have used with this terminal detect backspace correctly.

Incidentally, a standard 'xterm' works, but only because backspace produces a
'^H', which breaks all sorts of other apps.

Any help would be much appreciated.

Thanks,

Giles

Cone does not use termcap.  Cone uses terminfo.

Sorry, I meant terminfo.  Regardless, cone doesn't appear to work out of the
box with rxvt (also out of the box) or Eterm.  Do you know of a setting which
will cause it to detect backspace correctly?

Or gnome-terminal, or aterm, or konsole, or wterm, or xvt.  It works in the
linux console, and with an out of box xterm, both of which default to
emitting '^H' from the backspace key unless configured otherwise, at which
point, cone breaks there too.

Do I need to set any environment variables?

"stty -a" output for most terminals:

[snip]
        intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 =
<undef>; swtch = <undef>;
[/snip]


output for xterm (which uses '^H' incorrectly):

[snip]
intr = ^C; quit = ^\; erase = ^H; kill = ^U; eof = ^D; eol = <undef>; eol2 =
<undef>; swtch = <undef>;
[/snip]

Cone uses the terminfo to process keys.  You need to fix your terminfo
configuration.

Works fine for me on gnome-terminal.

Any ideas where to start?  It works with absolutely everything else, and doing
a quick test, hitting backspace definately produces the correct symbol.

Really?  What's your output from "stty -a"?  (particularly the 'erase' bit..)

And also under "compatibility" under "edit->current profile", what do you have
next to "Backspace key generates"?

I have "ASCII DEL", which is the default.

Same here.

Also: Delete key generates: escape sequence.
