CONS(4)                OpenBSD Programmer's Manual (VAX)               CONS(4)

NAME
     cons - VAX-11 console interface

DESCRIPTION
     The console is available to the processor through the console registers.
     It acts like a normal terminal, except that when the local functions are
     not disabled, ^P (control-P) puts the console in local console mode
     (where the prompt is `>>>'). The operation of the console in this mode
     varies slightly per-processor.

   Tn VAX No 11/780 or 785
     On either the VAX 11/780 or 785 the following commands may be used after
     placing the console in local mode with ^P.

         c
         continue  Re-enter conversational mode if the processor was halted.

         h
         halt      Halt the CPU.  On an 11/780 or 785 the processor is not
                   stopped by entering local console mode.

         set t p   (set terminal program) Re-enter conversational mode if the
                   processor is still running.

         P         (proceed) Get out of ODT mode.

         <break>   If you hit the break key on the console, then the console
                   LSI-11 will go into ODT (console debugger mode).

   Tn VAX No 11/750 or 11/730
     On an 11/750 or an 11/730 the processor is halted whenever the console is
     not in conversational mode.

         C         Return to conversational mode.

         ret       Return from remote diagnosis mode to local console mode.

         ^D        (11/750 only) When in console mode on an 11/750 which has a
                   remote diagnosis module, a ^D will put you in remote diag-
                   nosis mode, where the prompt will be

   Tn VAX No 8600 or 8650
     The VAX 8600 (8650) console normally works in the same way as the 11/750,
     except that there are many additional modes and commands.

         c
         continue  Return to conversational mode.

         halt      Halt the processor if HEX debug enabled.

         p         Halt the processor if in normal mode.

     With the above proviso's the console works like any other UNIX terminal.
