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 connec‐
tion is active. If a network console connection is not active, it redi‐
rects console output to an internal hardware interface.
The cvc driver receives console input from cvcredir and internal hard‐
ware 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
useful 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.
