CONSOLE(4D) Devices CONSOLE(4D)
NAME
console - STREAMS-based console interface
SYNOPSIS
/dev/consoleDESCRIPTION
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.

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.
