cvc(7D) Devices cvc(7D)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.
