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(4D) 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 "work‐
       station console" device consisting  of  the  workstation  keyboard  and
       frame  buffer  acting  in  concert  to  emulate  an ASCII terminal (see
       wscons(4D)).


       Regardless of the system configuration,  the  console  device  provides
       asynchronous  serial  driver semantics so that, in conjunction with the
       STREAMS line discipline module ldterm(4M), it supports  the  termio(4I)
       terminal interface.

SEE ALSO
       syslog(3C), termios(3C), msglog(4D), wscons(4D), termio(4I), ldterm(4M)

NOTES
       In  contrast to pre-SunOS 5.0 releases, it is no longer possible to re‐
       direct I/O intended for /dev/console to some other device. Instead, re‐
       direction now applies to the workstation console device using a revised
       programming interface (see wscons(4D)). Since  the  system  console  is
       normally  configured to be the work station console, the overall effect
       is largely unchanged from previous releases.


       See wscons(4D) for detailed descriptions of  control  sequence  syntax,
       ANSI control functions, control character functions and escape sequence
       functions.
