NAME
cons - PDP-11 console interface DESCRIPTION
The console is available to the processor through the console registers. It acts like a normal terminal, except that typing control-P on the consoles of some PDP-11's puts the console in local console mode with an ODT (console debugger mode) prompt. The operation of the con- sole in this mode varies per-processor. See the PDP-11 Processor Handbook for your particular processor. On an 11/44 the console can be put into local mode by typing a control-P. The ODT prompt is ``>>>''. The processor is not stopped by entering local console mode. The CPU may be halted with the ``halt'' command, which may be abbreviated to ``h.'' Conversational mode is re-entered by using the command ``c'' (continue). On 11/73 the processor's front panel halt switch must be pressed to put the console into ODT mode. The ODT prompt is an ``@''. No charac- ters typed on the console are special while UNIX is in control of the console. FILES

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.
