Orange binder: System Services References Manual, $BRKTHRU service.
USER1..16 are reserved for user-written images.

Now get out the little green binder!  :-)  You are running Jnet networking
software.  Jnet uses USER1..3 to control whether or not the host daemon
broadcasts network messages to you.  USER1 controls local user messages.
USER2 controls remote user messages.  USER3 controls messages not from any
user (such as SENT FILE... messages).

Jnet can be configured by using logical names to look at class names other
than USER1..3.
