Can't erase the backspace !

John Clifford_1 — Wed, 20 Feb 2002 10:56:06 GMT

This is probably more of a /etc/profile problem. I want to automatically erase the backspace for all users on the system. Normally one would type stty erase .
In the /etc/profile I put the line stty erase and then the sequence V . But when I logout and back in it doesn't seem to take.

Are you doing something in the local ~/.profile that overrides /etc/profile? Perhaps a 'tset' or 'stty' series of commands?

Share and Enjoy! Ian

Does the user's .profile have a "stty sane"?
I just tested - after doing a "stty sane", backspace does not erase characters on my terminal.

Hi,
On HP it should be:stty erase "^H"
Now, you havent mentionned what you are using (vt emulation, X like reflectionX ?) you might have to map the backspace in your emulator...

Just thoughts...

OK echo $TERM
xterm

I had the line stty erase ^? in my profile
and the backspace key would work as expected.. i.e. deleteing the previous character. I commented out the stty line and logged out and in and then the backspace key would no longer work; I would get ^?^?^? evertime I hit it. I also notice that stty erase "^H" was in the /etc/profile but obviously this hasn't had an effect.

Have you tried to enter something, like kjhswgkjhsfwf
Then do a and see if it erases?

Hi John,

the error you describe sounds as if you use RefletionX as emulator. If so, you can simply use the style manager "keyboard" to change behaviour with a mouse click.

Allways stay on the bright side of life!

NB /etc/profile has test only for VUE($VUE) not CDE($DT) for sty settings.

If you don't want to set erase in .profile you could use resources :

Create $HOME/.Xdefautls and put the following line in it:

*ttyModes: erase ^H intr ^C kill ^U start ^Q stop ^S swtch ^@ susp ^Z

for system wide settings use files in /usr/dt/config/C probably sys.resources.

Also bear in mind dtterm does not automatically reference a users .profile ... dtterm -ls will though.
