     mmeessgg - Display (do not display) messages from other users

     mmeessgg [nn | yy]

DDEESSCCRRIIPPTTIIOONN
     The mmeessgg utility allows a user to decide if other users may write mes-
     sages to his or her screen.  Programs such as talk(1), write(1) and
     echo(1) are social and display a message on the target user's terminal.
     Sometimes this is inconvenient.

     Options:

     nn	   Disallow messages, providing peace, and informing the contacting
	   party that `Your party is refusing messages'.

     yy	   Allow messages to be displayed.

     If no arguments are given, mmeessgg displays the present message status.

     The mmeessgg utility exits with one of the following values:

	    0	 messages are allowed
	    1	 messages are not allowed
	   -1	 An error has occurred.
