syscon(7)                        DG/UX 5.4.2                       syscon(7)


NAME
       syscon, console, systty - DG/UX operating system console pseudo-
       device

DESCRIPTION
       The DG/UX system uses the notion of an "operating system console,"
       which is the terminal on which initial system administration is
       performed and to which various messages from the kernel are written.
       By necessity, this terminal is also the terminal (physical system
       console) used by the system administrator to communicate with the
       processor when the operating system is not running.

       The actual device which provides the physical system console
       interface depends on the hardware configuration of the system.
       However, regardless of the actual system configuration, the DG/UX
       operating system console is accessible only through the syscon
       pseudo-device interface, using the file node /dev/syscon.  This
       device provides the standard DG/UX terminal interfaces (termio(7)),
       except that changes to hardware settings such as baud rate, stop
       bits, and parity have no effect.

       NOTE:   The terminal type of the graphics console on AViiON
               workstations is avx300, not vt100.  You must set the
               environment variable TERM to avx300 when using the man(1)
               command.
