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

Logically, the cvc driver sits below the console driver. It redirects console output to the cvcredir(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.

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

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.
