console(7D)

NAME

     console - STREAMS-based console interface

SYNOPSIS

     /dev/console

DESCRIPTION

     The file /dev/console refers to the system  console  device.
     /dev/console  should  be used for interactive purposes only.
     Use of /dev/console for  logging  purposes  is  discouraged;
     syslog(3C) or msglog(7D) should be used instead.

     The identity of this device depends on the EEPROM  or  NVRAM
     settings  in  effect  at  the  most recent system reboot; by
     default, it is the ``workstation console'' device consisting
     of  the workstation keyboard and frame buffer acting in con-
     cert to emulate an ASCII terminal (see wscons(7D)).

     Regardless of the system configuration, the  console  device
     provides   asynchronous  serial driver semantics so that, in
     conjunction  with  the  STREAMS   line   discipline   module
     ldterm(7M), it supports the termio(7I) terminal interface.

NOTES

     In contrast to pre-SunOS 5.0 releases, it is no longer  pos-
     sible  to  redirect  I/O  intended  for /dev/console to some
     other device. Instead, redirection now applies to the works-
     tation  console device using a revised programming interface
     (see wscons(7D)). Since the system console is normally  con-
     figured  to  be the work station console, the overall effect
     is largely unchanged from previous releases.

     See wscons(7D) for detailed descriptions of control sequence
     syntax,  ANSI control functions, control character functions
     and escape sequence functions.
