.SH NAME
cvc \- virtual console driver
.SH DESCRIPTION
.sp
.LP
The \fBcvc\fR virtual console driver is a STREAMS-based pseudo driver that
supports the network console. The \fBcvc\fR driver interfaces with
\fBconsole\fR(7D).
.sp
.LP
Logically, the  \fBcvc\fR driver sits below the  \fBconsole\fR driver. It
redirects console output to the \fBcvcredir\fR(7D) driver if a network console
connection is active. If a network console connection is not active, it
redirects console output to an internal hardware interface.
.sp
.LP
The \fBcvc\fR driver receives console input from  \fBcvcredir\fR and internal
hardware and passes it to the process associated with \fB/dev/console\fR.
.SH NOTES
.sp
.LP
The  \fBcvc\fR facility supersedes the SunOS \fBwscons\fR(7D) facility, which
should  \fInot\fR be used in conjunction with  \fBcvc\fR. The  \fBwscons\fR
driver is useful for systems with directly attached consoles (frame buffers and
keyboards), but is not useful with platforms using \fBcvc\fR, which have no
local keyboard or frame buffer.
