     Description:

	PHONE is a utility which allows you to talk to other users on  your
     system.  Once PHONE is started, the screen of the VT100 (only terminal
     supported)  is split into two viewports.  After you dial someone, what
     you  type  is  displayed  in  the top viewport and what the other user
     types  is displayed in the bottom viewport.  At the current time, only
     two  users can talk at the same time.  When your phone conversation is
     complete,  typing  CTRL/Z  returns you to the command prompt (%) where
     you can exit by typing either another CTRL/Z or by typing EXIT and the
     return key.

     Command line format:  PHONE [phone-command]

	You may specify a command as part of the PHONE command line, or
	you may enter it at the command prompt (%).

     NOTE:

	The PHONE utility is taskbuilt /PR:0 because it does a write-break
     through  QIO  to the terminal you want to talk to.  Our catchall task
     allows  non-privileged  users to run certain privileged tasks such as
     PHONE, USERS, and WHO. If you don't have this capability then you may
     want  to modify PHONE so it can be run by non-privileged users.  This
     would be done by removing the /PR:0 switch from the taskbuild command
     file,  and  by  changing the IO.WBT function in module DIAL.MAC to an
     IO.WLB  function.  Also note that the phone task must be activated by
     the  command line "RUN PHONE/TASK=PHOTnn" where "nn" is your terminal
     number.

	The  above  restriction  actually only applies to RSX-11M.  On M+,
     simply  install  the  privileged  version  of PHONE for it to operate
     properly.  This is because on M+, all tasks are started with the task
     name  "taskTnn"  where on RSX-11M, the first task starts up under the
     task  name  "...PHO"  which  causes a problem since the phone program
     uses the terminal number from the task name.
