CONSOLETYPE(1) General Commands Manual CONSOLETYPE(1)NAME
consoletype - print type of the console connected to standard input
SYNOPSIS
consoletype [stdout] [fg]
DESCRIPTION
consoletype prints the type of console connected to standard input, and checks whether the console connected to standard input is the cur-
rent foreground virtual console. With no arguments, it prints vt if console is a virtual terminal (/dev/tty* or /dev/console device if not
on a serial console), serial if standard input is a serial console (/dev/console or /dev/ttyS*) and pty if standard input is a pseudo ter-
minal.
RETURN VALUE
consoletype when passed no arguments returns
0 if on virtual terminal
1 if on serial console
2 if on a pseudo terminal.
When passed the stdout argument, consoletype returns
0 in all cases, and prints the console type to stdout.
When passed the fg argument, consoletype returns
0 if the console connected to standard input is the current virtual terminal
1 otherwise.

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 concert 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.
SEE ALSO syslog(3C), termios(3C), ldterm(7M), termio(7I), msglog(7D), wscons(7D)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(7D)). Since the system console
is normally configured 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.
