3. VT100 Interface
Cursor Controls
The VT100 interface uses a blinking cursor to select various menus and then to
select sub-menus and/or fields within those menus. You can navigate using this
cursor in different ways, depending on the program you use. Most programs allow
use of the Tab key and the Shift+Tab keys. Others allow use of the arrow keys.
NOTICE:
For keyboards that do not have these standard keys or have only some of them,
an alternative set of cursor control commands is provided. Perform each
command by pressing a letter key while holding down the Ctrl key. You may use
the alternative commands and keyboard commands listed below interchangeably
at your discretion.
You can navigate further within a menu as described below.
Field Types
Each menu screen is composed of fields. The two basic field types are
user-selectable (most of these are in brackets or parentheses) and display-only
(no brackets or parentheses). If you can move the highlighted cursor to a field, that
field is user-selectable; all other fields are display-only. User-selectable fields are
those in which you can make changes or execute commands. To save changed
parameters, press the Enter key while on any user-selectable field or link to a
submenu (screen). If you make changes to a screen and then Esc out of the
screen, you will see a prompt at the bottom of the screen: Save Changes (Y) or
Discard Changes (N). To save changes, press Y or y; to discard changes, press N
or n or Esc. If the VT100 session times out, you will be logged off without the unit's
having saved any changes.
Fields enclosed in brackets [ ] offer a list of selections from which to choose. The
selections may be made by pressing your Spacebar to toggle between choices.
Each time the Spacebar is pressed, a new item appears. When the item you wish
to choose is displayed, press the Esc key to save it.
Fields enclosed in parentheses ( ) are manipulated by one of the following two
methods. The first is to press the Enter key to simply execute the function. The
most common type of field in parentheses accepts typed input in the form of letters
and/or numbers. Typing characters when the field is highlighted causes the current
entry to be replaced by the new characters. To edit an existing entry rather than
replace it, press the right arrow key to move the cursor to the point that needs
