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.
VAX-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).
VAX-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
diagnosis mode, where the prompt will be
‘
RDM>
’.
VAX-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.
