[net.emacs] Getting EMACS's attention

cef@spice.cs.cmu.edu.ARPA (Charles Fineman) (10/15/85)

I have a set-up like this:

	+-----------+                +--------+       +-------+
	| Process X | <------------> | Driver | <---> | EMACS |
	+-----------+                +--------+       +-------+

What I need is a way for the driver, upon recieving a signal from Process X,
to gain control of EMACS. E.G. Suppose Process X is a menu: I want to be able 
to select an entry from the menu and have emacs go to that section of the
file. Is there a way to do this without hacking up EMACS itself?
