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
``workstation 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.

NOTES

In contrast to pre-SunOS 5.0 releases, it is no longer possible to
redirect I/O intended for /dev/console to some other device. Instead,
redirection 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.
