break (C-c C-C) in shell broken

break (C-c C-C) in shell broken

[fred]

I am using all the time a shell window from emacs and it 
used to be the case that Control-C Control-C would send a 
break to the shell. It is a feature I use all the time
(specially when doing SQL queries).
However, it stopped working just recently. 
Local unix system engineers couldn't help. 

I use: 
GNU Emacs 21.2.1 (sparc-sun-solaris2.8, Motif Version 2.1.0) of 2002-09-10 
GNU bash, version 2.03.0(1)-release (sparc-sun-solaris)

I also tried to recompile and reinstall emacs today with no success. 

Any help would be greatly appreciated. thanks.

fred.

What does C-h k C-c C-c say in the situation where you would like it
to send a break to the shell?

What happens when you type C-c C-c to send a break to the shell?

C-c C-c runs the command comint-interrupt-subjob
   which is an interactive compiled Lisp function in `comint'.
(comint-interrupt-subjob)

nothing. When selecting it from the menu bar, it says
'menu-bar signals break' in the minibuffer window. But still doesn't
break.

Thanks.

Hm.  C-c C-c is invoking the right command, but the command doesn't
do anything.

I have no idea how come this happens.  Hm.  I would perhaps locate
the source for the function (M-x find-function RET
comint-interrupt-subjob RET), then M-x edebug-defun RET it, then
single-step through it to see what happens.

I was told a work-around:
 typing C-q C-c C-q C-c and then enter
which is working.

Maybe now somebody may have an idea on what could have broken the C-c C-c
command, and how to fix it ? 

thanks.

Fred.

Nice tip thanks.  I have been relying on 'end process' from task
manager to stop hung processes.

Is it broken in the cvs version?  I'm using 21.3.
