MULTISCREEN(M)                       UNIX System V



     Name
          multiscreen - multiple screens (device files)


     Syntax
          alt-Fn
          alt-ctrl-Fn
          alt-shift-Fn
          alt-ctrl-shift-Fn


     Description
          With the multiscreen feature, a user can access up to twelve
          different  ``screens,''  each  corresponding  to  a separate
          device file.  Each screen  can  be  viewed  one  at  a  time
          through the primary monitor video display.

          The number of screens on a system depends upon the amount of
          memory  in  the  computer. The system displays the number of
          enabled screens during the boot process.

     Access
          To see the next consecutive screen, enter:

               Ctrl-PrtSc

          To move to any screen from any other screen, enter:
          alt-Fn or alt-ctrl-Fn or alt-shift-Fn
          alt-Fn or alt-ctrl-Fn (screens 1-12)
          alt-shift-Fn or alt-ctrl-shift-Fn (screens 11-16, 7-12)
          where n is the number of one of the ``F'' function  keys  on
          the primary monitor keyboard.  For example:
          alt-F2
          selects tty02, and all output in that device's screen buffer
          is displayed on the monitor screen.

          The second form (using the  SHIFT  key)  permits  access  to
          screens  11  and 12 on keyboards that have only ten function
          keys.  It is also possible to configure the kernel for up to
          16 screens, but 12 is the default.

          The function key combinations used to  display  the  various
          screens  are  defined  in  the  keyboard  mapping  file. The
          /usr/lib/keyboard/keys or  other  mapkey(ADM)  file  can  be
          modified  to  allow  different  key  combinations  to change
          multiscreens.  Use  the  mapkey  utility  to  create  a  new
          keyboard map.


     Files
          /dev/tty[01-12]          multiscreen devices
                         (number available depends on system
                         memory)


     See Also
          mapkey(ADM), keyboard(HW), screen(HW), serial(HW), stty(C)


     Notes
          Any system error messages are normally output on the console
          device  file  (/dev/console).   When  an  error  message  is
          output, the video display  reverts  to  the  console  device
          file,  and  the  message  is  displayed  on the screen.  The
          console device is the only teletype device open  during  the
          system  boot  sequence  and  when  in single user, or system
          maintenance mode.

          Limitations to the number of  multiscreens  available  on  a
          system does not affect the number of serial lines or devices
          available. See serial(M) for information on available serial
          devices.

          Note that the keystrokes given here  are  the  default,  but
          your  keyboard may be different.  If so, see keyboard(M) for
          the  appropriate  substitutes.   Also,  any   key   can   be
          programmed  to  generate  the  screen switching sequences by
          using the mapkey utility.


     Value Added
          multiscreen is an extension of AT&T System V provided by the
          Santa Cruz Operation.
