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.
