save-buffers-kill-emacs from remote unix signal?

[GNU emacs 22.0.50.1 sparc-sun-solaris2.9 X-toolkit]
Is there some way I can use a unix signal to remotely cause
emacs to save-buffers-kill-emacs without query,
i.e. as if I had typed ^U^X^C ?   If I leave emacs up in my
office with many unsaved buffers, I'd like to log in from home
and do "kill -something <emacs-pid>" and have it save all
buffers unconditionally and exit.

I know that I can just kill the emacs and reconstruct things from
autosave files, but I operate with *many* active buffers and this
gets to be quite difficult and error prone.

The Multi TTY branch can solve your problem or a bit more
complicated tunnel X via ssh and create a frame on our
$DISPLAY at home using emacsclient.

You could use the Emacs Server (put (server-start) in your .emacs).
Then you can call "emacsclient -e '(save-buffers-kill-emacs t)'".

Does this work (-something is -USR1):

;; See the Misc[ellaneous System] Events node of the Emacs Lisp manual:
(global-set-key [usr1-signal]
		(lambda ()
		  (interactive)
		  (save-buffers-kill-emacs t)))

Yes!  That works perfectly!  Thanks very much.
