USING DUPLEX
 
          DUPLEX is a program that allows one  to  talk  to  the  treatment
          planning  computer (the 11/45) from any terminal on the main sys-
          tem, (the 11/44).  Only one person at a time can use DUPLEX, (be-
          cause there is only one spare terminal interface on the 11/45.)
 
          Use is as follows:
 
 
               1.  Log on to 11/44 system in the normal way.
 
               2.  Evoke DUPlex MCR>DUP<cr>
 
                   (Duplex is now active and the effect is the same  as  if
                   you  had  physically  re-connected  your terminal to the
                   11/45.)
 
               3.  Type another control-C to activate HELLO or MCR  on  the
                   11/45.
 
               4.  Due to hardware limitations, operation on the  11/45  is
                   limited to 300 BAUD.
 
               5.  After performing operation, (i.e.  entering  calibration
                   data,) log off the 11/45 in the normal way.
 
               6.  To get out of DUPlex state, type a control-B.  (You  can
                   do  this at any time, but you will leave yourself logged
                   in on the 11/45.)
 
               7.  After typing the control-B, you may have to type another
                   control-C to get MCR back.
 
               8.  REMEMBER, if DUPlex is running, a control-C gets MCR  on
                   the  11/45, if DUPlex is not running, control-C gets MCR
                   on the 11/44.
 
          Note that DUPLEX also has the capability  of  transmitting  ascii
          data between the two systems.  See AID DUP for help.
