The console is the only terminal from which you can execute a special subset
of commands, called console commands. They are used for two purposes:
To allow you to communicate with the computer when you cannot get
the normal system prompt.
To perform specific tasks that affect the entire computer system, such
as stopping all jobs and sessions and shutting down the computer.
The console commands are listed below.
To issue any of the console commands, you first generate the control-A
(=) prompt. To do so, hold down the CTRL key and
press A. The control-A (=) prompt is displayed on your screen.
The commands you have been using at the system prompt (:) no longer work.
To get the system prompt back, press RETURN a few times.

 | CAUTION: Do not enter the LOGON, LOGOFF, or SHUTDOWN commands at
the "=" prompt until you know exactly what you are doing. These commands
are extremely powerful and must be used only during a standard shutdown. |

To move the console |
|
You can move the console without physically moving your terminal. The console is a set of capabilities, including commands and two special prompts, that allow one terminal to communicate with and control the computer.
To move the console, enter:
nn is the device number of the terminal you are moving the console to.
To allow users to access the console |
|
Use the ALLOW command to distribute specific operator commands to
system users. The ALLOW command specifies which users may execute
operator commands and which commands the users may execute.
For example, to give the user USER.TECH the ability to execute the
REPLY and ABORTIO commands, enter the following at the system console:
ALLOW USER.TECH;COMMANDS=REPLY,ABORTIO
|
You may distribute console capabilities only to users who are currently
logged on to the system, unless the @.@ option of the ALLOW command
is used. In this case, all users are affected, whether or not they are
logged on. Additional capabilities granted to a user are valid only for
the duration of their current session. Once the user logs off, any special
capabilities previously assigned are no longer applicable.
