options selection.
Up arrow key also called the MENU key, is used for vertical
menu selection and is used to access the previous menu. The up
arrow key also serves as a quit command when you want to stop the
current action.
Down arrow key also called the ENTER key, is used solely to
register the chosen selection and is very similar to the CARRIAGE
RETURN key or ENTER key on a standard keyboard.
MENU TREE
Fig. 4-1 shows the menu tree structure. There are two main menu trees. One is the
CONFIGURATION menu, the other is the DIAGNOSTIC menu. Fig. 4-2 shows the submenus
under the CONFIGURATION menu. In Fig. 4-1, there is one idle screen and four data state
screens. In data state, screen (1) to (4) can be accessed by pressing the left or right arrow key. A
dialing menu can be accessed from the idle screen. Flip between idle screen and menu screen
by pressing the MENU or up arrow key.
LED STATUS SCREEN
Either in idle state or data state, there is an LED status screen
that can be accessed and displayed by pressing the left or right
arrow key at the menu's top level. This LED status screen has
five status indicators - DCD, DSR, CTS, RTS, and SQ. These status
indicators are identical to the LED indicators of the non-LCD
modems. Some of the status indicators are better expressed by
other screen displays, e.g., a data state screen means DCD is on,
and an idle screen means DCD is off; SQ is better explained by
S/N ratio and other impairment readings.
ARROW ON THE SCREEN
In some menu screens, you will see double left arrows (<<) or
double right arrows (>>). This means there are more items on the
left or right. Use the left or right arrow key to select them. If
you can only see a double right arrow, this indicates that the
current item is the first item of the menu. By pressing the left
arrow key, the screen will wrap over to the last item. On the
other hand, if you only find a double left arrow displayed, this
indicates that your current item is the last item in that menu.
Similarly, pressing right arrow key at this point will cause the
screen to wrap around to the first item.
DIALING
From the IDLE SCREEN (1) of Fig. 4-1 you can use the right or
left arrow key to scroll through D, R, O, and A. Move the
blinking cursor to "D", press ENTER, and you will go into the
Dialing Directory.
Valid digits/characters for dialing are:
0 1 2 3 4 5 6 7 8 9 * #
, Pause
