Command: ANNOUNCE  This command is used to send a text string out to all
                   stations which are connected to the PacketCluster.  If you
                   wish to make announcement to only those users connected to
                   a particular PacketCluster node, you can specify the call
                   of the node on the command.  The ANNOUNCE command defaults
                   to the local node; a cluster-wide announcement requires 
                   using the /FULL qualifier on the command.  You can also
                   specify a distribution list as a qualifier.  The ANNOUNCE 
                   command may be used while in Conference Mode or 
                   Talk Mode by prefacing it with an asterisk (*).
