Adding/Editing Users

Session Timeout The amount of time, in seconds, before the IOLAN forcibly closes a user’s session (connection). The default value is 0 (zero), meaning that the session timer will not expire (the session is open permanently, or until the user logs out). The User Session Timeout will override all other Serial Port Session Timeout parameters.

Range: 0-4294967

Default: 0

Enable Callback When enabled, enter a phone number for the IOLAN to call the user back (the Enable Callback parameter is unrelated to the Serial Port Remote Access

(PPP)profile Dial parameter).

Note: the IOLAN will allow callback only when a user is authenticated. If the protocol over the link does not provide authentication, there will be no callback. Therefore, when the Serial Port profile is set to Remote Access (PPP), you must use either PAP or CHAP, because these protocols provide authentication.

The IOLAN supports another type of callback, Roaming Callback, which is configurable when the Serial Port profile is set to Remote Access (PPP).

Default: Disabled

Phone Number The phone number the IOLAN will dial to callback the user (you must have set Enable Callback enabled).

Restrictions: Enter the number without spaces.

Language You can specify whether a user will use English or Custom Language as the language that appears in the Menu, CLI, or WebManager. The IOLAN supports one custom language that must be downloaded to the IOLAN.

Default: English

See Language Support on page 316 for more information about Custom Languages.

Hotkey Prefix The prefix that a user types to control the current session.

Data Options:

z^a number—To switch from one session to another, press ^a (Ctrl-a) and then the required session number. For example, ^a 2 would switch you to session 2. Pressing ^a 0 will return you to the IOLAN Menu.

z^a n—Display the next session. The current session will remain active. The lowest numbered active session will be displayed.

z^a p—Display the previous session. The current session will remain active. The highest numbered active session will be displayed.

z^a m—To exit a session and return to the IOLAN. You will be returned to the menu. The session will be left running.

z^a l—(Lowercase L) Locks the serial port until the user unlocks it. The user is prompted for a password (any password, excluding spaces) and the serial port is locked. The user must retype the password to unlock the serial port.

z^r—When you switch from a session back to the Menu, the screen may not be redrawn correctly. If this happens, use this command to redraw it properly. This is always Ctrl R, regardless of the Hotkey Prefix.

The User Hotkey Prefix value overrides the Serial Port Hotkey Prefix value. You can use the Hotkey Prefix keys to lock a serial port only when the serial port’s Allow Port Locking parameter is enabled.

Default: Hex 01 (Ctrl-a or ^a)
