emacs ctrl-m is RET. how to change for rebinding ?

[Stefan Horomnea]

Hello,

I want to bind Ctrl-m to a function in .emacs, with:
(global-set-key [?\C-m] 'delete-backward-char)

But then, I discover that I bound "enter" to that function, cause Ctrl-m 
is enter. How to solve this problem ? I want to insert newline with 
enter and do delete-backward-char with Ctrl+m.

I googled for a very long time for this, but couldn't find the solution.

Thanks for your help

When running in a tty, you don't get to choose: The `return' key sends a C-m
and that's all Emacs will ever see.

When running under X11, Emacs can indeed tell the difference.  The `return'
key is mapped to C-m via function-key-map, so all you need to do is to bind
[return] explicitly to a command like `newline' and the mapping to C-m will
not happen:

  (global-set-key [return] 'newline)

And now your minibuffer is broken.
