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 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.

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.

NAME

       cvc - virtual console driver

DESCRIPTION

       The  cvc  virtual  console  driver  is a STREAMS-based pseudo driver that supports the network console. The cvc driver interfaces with con-
       sole(7D).

       Logically, the  cvc driver sits below the  console driver. It redirects console output to the cvcredir(7D) driver if a network console con-
       nection is active. If a network console connection is not active, it redirects console output to an internal hardware interface.

       The cvc driver receives console input from  cvcredir and internal hardware and passes it to the process associated with /dev/console.

NOTES

       The   cvc facility supersedes the SunOS wscons(7D) facility, which should  not be used in conjunction with  cvc. The  wscons driver is use-
       ful for systems with directly attached consoles (frame buffers and keyboards), but is not useful with platforms using cvc,  which  have  no
       local keyboard or frame buffer.
