Are you resetting any of erase or erase2 in your shell startup files with stty? There is a statement in the /etc/bashrc file: stty erase `tput kbs` Hmmm. Why? Try commenting out that .bashrc part. What is `kbs' supposed to be anyway? The termcap(5) manpage doesn't mention a kbs capability. Giorgos.

Re: backspace and del keys
Figured it out for xterms. Readline(3) uses an initialization file .inputrc to customize commands. There was no inputrc file in the system si I added one in etc and set INPUTRC=/etc/inputrc in the /etc/bashrc file. I actually took the file from my Linux system but is has the following line. \e[3~: delete-char This works fine in X but does not change the virtual consoles. That is not a problem because I rarely use them. The best thing about it is that I have learned quite a bit during this little exercise. You assistance is greatly appreciated.

Good use of hd.
I get 08 (BS) instead of 7f.
And tput kdel gives 1b 4f 42.
As long as the two give different codes, his shell can translate them
as he likes, and he needn't fix lower-level key config. Of course,
it doesn't change things for other apps.
I found kbs in /usr/X11R6/lib/X11/etc/xterm.terminfo, but it doesn't
have kdel, so I doubt if that's the source of even kbs.
Oh well. I've learned to live in ignorance when it comes to keys and
fonts (among other things).

I have tried this inthe virtual console tty, XTerm, Konsole, and ETerm and they pretty much behave the same. This was done at the command line in sh, csh, and bash. It was also tried in vim and Some GUI apps like Evolution. At the virtual console tty pressing the Delete key deletes the character to the left of the cursor rather than the one below it. In XTer and ETerm is insets a tilde character. To get XTerm to generate a DEL when you hit the Delete key, you need to add the following line into ~/.Xdefaults: xterm*deleteIsDEL: true -- Jonathan Chen [EMAIL PROTECTED] -- Do not take life too seriously.
