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.
