DESCRIPTION

       The  cvcredir  virtual console redirection driver is a STREAMS-based pseudo driver that supports the network console provided on some plat-
       forms. The cvcredir driver interfaces with the virtual console driver cvc(7D), and the  virtual console	daemon,  cvcd(1M).

       The  cvcredir driver receives console output from cvc and passes it to  cvcd. It receives console input from  cvcd and passes it to  cvc.
