cvcredir, the virtual console redirection driver, is a STREAMS-based pseudodriver that works in conjunction with the cvc driver, cvc(7), and the cvc daemon, cvcd(1M).
The cvcredir device is opened at start-of-day by the cvc daemon, cvcd(1M). cvcredir receives console output from cvc(7) and passes it to cvcd(1M). It receives console input from cvcd(1M) and passes it to cvc(7).
