Option: XMR-UCI-RCV

This option is the converse to another called "SEND MESSAGES TO OTHER UCI".
 3.  Log onto the UCI you wish to receive the messages into.
 4.  Use this option.  It will read through the %ZISL(4.281 global looking
     for a message to receive (don't worry, it only checks the first line
     of each potential message/task) and creates a message for them.
Requirements:
 1.  The receive side needs to have been set up as a domain.
 2.  The %ZISL(4.281 global must be translated and accessible from both UCIs.
The SEND side loads messages into the %ZISL(4.281 global.
The RECEIVE side reads messages from the %ZISL(4.281 global.
To use:
 1.  Log onto the UCI you wish to transmit message from.
 2.  Use the SEND option.  It will load all the messages for a particular
     domain into ^%ZISL(4.281.
