break signal on Mac OS X doesn't work

[David Goodger]

System identification: I'm running GNU Emacs 21.3.50.1 on Mac OS X
10.3.7.  It runs in a window that starts out saying "Terminal" in the
title bar, before Emacs takes over.  My .emacs file contains this
setup code:

; shell mode
(setq explicit-shell-file-name "bash")
(setq explicit-bash-args '("--login" "--noediting" "-i"))
(add-hook 'shell-mode-hook 'my-shell-mode-hook)
(defun my-shell-mode-hook ()
  "Customize shell-mode"
  (define-key shell-mode-map "\C-cf" 'font-lock-mode)
  (define-key shell-mode-map '[C-return] 'shell-enter-and-resync-dirs)
  (setq tab-width 8)
  (setq font-lock-mode nil))

The problem is when I open a shell ("M-x shell"), I can't stop a
process with a BREAK signal (typing C-c C-c or choosing BREAK from the
Signals menu).  I see "C-c C-c" in the shell window, but the process
doesn't halt.

Any clues to what's going on here?  Thanks in advance.
