The SET PRIVILEGED command can only be used from the supervisor port of
the MUXserver 100. (See Section 3.1.4, Remote Management of the
MUXserver 100 (By Means of the E:thernet).
Password security also exists on the supervisor port of each DECmux II unit.
To maintain security these should also be change regularly. (Refer to Chapter
2, Section 2.2.2, Setting Up the Password On the DECmux II.)
3.1.2 Service Mode Managernent
As the server manager, you can control the terminal users' access to service
mode. In Chapter 2, Section 2.4 (SETTING UP THE SERVER CHARACTER-
ISTICS) to Section 2.7 (SETTING UP THE PORT CHARACTERISTICS) de-
scribe how to use terminal and server characteristics to do this. You can also
use the privileged form of several MUXserver 100 commands.
As the server manager, you can use the privileged form of the LOGOUT com-
mand to log out any of the ports. The port you specify can be of any type,
including the users' interactive ports. The command terminates all service ses-
sions at the specified port. For examlple, to disconnect port 4 from all its ses-
sions, enter the following:
LOCAL> LOGOUT PORT 4
Use caution when logging out a user's port. When you log out a port you ab-
ruptly stop all service sessions and data may be lost.
3.1.3 Communication with
TE~rminal
Users
The privileged BROADCAST command lets you send messages to one particu-
lar terminal or to all the terminals. This command can help you manage the
server and terminals. For example, if you change the group codes for the termi-
nals, you can use BROADCAST to alert the users of the change.
Here is a BROADCAST command that transmits the message, "You can now
use the service RESEARCH", to terminal or port 3.
LOCAL> BROADCAST PORT 3 "You can now use the service RESEARCH"
The following command sends the same message to all the terminals.
LOCAL> BROADCAST ALL "You can now use the service RESEARCH"
