NAME

cvc- virtual console driver

DESCRIPTION

cvc is a STREAMS-based pseudodriver that supports the network console, which is called cvc on the host side and netcon on the SSP. cvc 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 the JTAG interface.

The cvc driver receives console input from cvcredir 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 the Enterprise 10000 system, which has no local keyboard or frame buffer.
