Without further description of your problem, this is about as much advice as anyone can suggest. FYI, the terminfo database has changed a few times, and I'm not at all certain that the 'kbs' value stayed intact. On my system, 'tput kbs' prints ASCII BS. It doesn't and I think it shouldn't. Or is there some Cygwin specific extension in the stty program that does what I want? I don't see anything in stty(1). I still think 'stty' is what you want. Another place to look is the shell initialization files (e.g., the default /etc/profile has a bash-specific section that issues 'stty erase ^?' -- has that section become bash-specific recently?). Alternatively, look at the CVS history of fhandler_console.cc in winsup/cygwin. That should tell you if anything changed WRT the character produced by BackSpace.

All the 'stty erase' setting does is to select the 'character delete' code for use in 'simple' terminal input (e.g. from applications like ftp as opposed to shells which handle line editing themselves).

Re: Map Backspace to ASCII DEL?
Hello Ian, my apologies, I'm still learning english;) Currently it seems that the cygwin terminal sends ^H (ASCII BS, 0x08) for backspace, and the VT220 Remove escape sequence (\E[3~, 0x1B5B337E) for Delete. I'd like it to send ^? (ASCII DEL, 0x7F) so that ^H can be used by applications (e.g. emacs). This is how I've always configured # \C-h: backward-delete-char # \C-?: backward-delete-char At least I found the Bash builtin bind: bind -u backward-delete-char removes all bindings for the Backspace key so you can define ^H yourself with another Function.

This works for bash and probably other shells that use readline. Hi Gerrit, Thanks, but like stty this is too high level. This only tells applications that use the readline library what to do when they receive a certain character or string from the terminal. Readline, termcap/terminfo, and stty settings only change how the applications that use them react to a certain character/string. I'm looking to change the character/string that is sent to them for a particular keycode. In general it is a lot easier and there is a lot less to configure if the ASCII DEL character is sent for the Backspace keycode, and this also frees ASCII BS, or ^H, to be used by applications such as emacs. I would like to use Cygwin as my terminal and via ssh access several different machines, so minimizing the configuration required at each system is important. If I was on a Linux box I would accomplish this locally by changing the keymap using loadkeys, but this doesn't appear to be a part of the Cygwin port (and for all I know it may not be sensible on account of the Cygwin/Windows low-level details?).

I use Exceed as my local X server and it has a xmodmap equivalent. It's nice because I can use the mouse for cut/copy/paste, but it is somewhat slow. For a quick session the cygwin terminal would be much more efficient, if I could get it to function properly!

Here's another tip: Instead of wildly long invocation lines use ~/.Xdefaults to specify things that are common and possibly to create term types then use rxvt -name... For example, instead of $ rxvt -fn Lucida Console-*-15 -sl 500 -backspacekey ^? -deletekey ^? \ -bg # -fg Whtie -colorBD Blue -colorUL Red -cursor Red You can just do rxvt for your default rxvt.

Re: Map Backspace to ASCII DEL?
Hi, Thanks for the reply. I had tried that, but it seems to have no effect. If I type C-v Backspace I still get ^H... ~$ stty -a | grep erase intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = undef; ~$ ^H I believe that just tells the terminal what to do on the line when it receives ^?, but it this case it is not, it's getting ^H.
