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.
