6 cvc - virtual console driver
7
9 The cvc virtual console driver is a STREAMS-based pseudo driver that
10 supports the network console. The cvc driver interfaces with con‐
11 sole(7D).
12

14 Logically, the cvc driver sits below the console driver. It redirects
15 console output to the cvcredir(7D) driver if a network console connec‐
16 tion is active. If a network console connection is not active, it redi‐
17 rects console output to an internal hardware interface.

20 The cvc driver receives console input from cvcredir and internal hard‐
21 ware and passes it to the process associated with /dev/console.
22
24 The cvc facility supersedes the SunOS wscons(7D) facility, which
25 should not be used in conjunction with cvc. The wscons driver is
26 useful for systems with directly attached consoles (frame buffers and
27 keyboards), but is not useful with platforms using cvc, which have no
28 local keyboard or frame buffer.
