8.8.4.2 Inactivity Logouts
To configure a port to log out after a specified period of inactivity, use the Set/Define Ports Inactivity
Logout command. This command works in conjunction with the Set/Define Server Inactivity command.
The latter defines a particular number of minutes; after this period of time, a port with Inactivity Logout
enabled will be considered inactive and automatically logged out.
Note: Set/Define Server Inactivity is described on page 12-120.
To enable Inactivity Logout, use the following command:
Figure 8-25: Enabling Inactivity Logout
The SCS will only perform an inactivity logout when the port is in character mode (not running PPP or
SLIP). To configure idle time logouts for PPP and SLIP connections, you must configure an idle time for
the site; after the site is idle for the specified time, the link will be shut down. Use the Define Site Idle
command and specify the length of the idle time limit in seconds.

8.8.5 Restricting Commands
The Security characteristic may be used to limit a user’s access to information about other ports. When
Security is enabled, only a limited number of commands may be typed at the Local> prompt. A user on a
secure port are unable to get information about other ports using the Show/List commands and can not
perform commands which require privileged access.
To enable Security on a particular port, use the Set/Define Ports Security command.

8.8.6 Receipt of Broadcast Messages
The Set/Define Ports Broadcast command enables or disables a port’s receipt of broadcast messages from
other users, including the superuser. Broadcast messages are enabled by default.
Figure 8-28: Disabling Broadcast Messages
Broadcast messages are also discussed in Sending a Broadcast Message on page 2-5.
