NAME

6       cvc - virtual console driver
7

DESCRIPTION

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
13
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.

NOTES

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.
