syscon(7)                  DG/UX 4.30                   syscon(7)



     NAME
          syscon - 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), tty(7)),
          except that changes to hardware settings such as baud rate,
          stop bits, and parity have no effect.
