Setting or Modifying Fields

2

The Field Sensitive Help Line offers help while certain fields are selected. The Event Message Line reports the status of certain field-related actions (e.g.: “Saved OK” or “Bad Value”).

1.Use the Tab key or arrow keys to highlight fields.

2.Set the new value:

With toggle fields (those that appear in square brackets), use the Return key to scroll through to the desired option.

There are two edit methods available in each editable field. All editable fields offer the same first method: replace the entire current string simply by typing into the field. As for the second method, some fields offer “return to default,” others offer “overstrike.” If a field has a default value, the default may be restored simply by selecting the field and pressing Return. If the field has no default, pressing Return activates the overstrike mode whereby the user may use the arrow keys to move through the current string and replace individually selected characters by typing new ones in their place. Press Return again to exit overstrike mode.

3.Invoke the SAVE command at the bottom of the screen to store all settings currently shown on the screen, or skip this step to throw away all recent screen edits since last save when exiting the screen.

If a user with an ineligible access level attempts to edit a restricted-access field, a message of refusal appears on the Event Message line. Refer to Section 5.4.2, Access Policy for details.

Exiting the Local Management Interface Session

3

1.Return to the Main Menu by invoking RETURN on each screen.

2.Invoke the Main Menu’s EXIT LM command to close the session and return to the Password Screen. (Enter a password to regain entry.)

The user may leave the connection active, or simply disconnect the terminal or stop the emulator program.
