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

In command state, there are three main menu trees. The IDLE menu is the default, and can be accessed after the modem is powered on or reset. The second is the CONFIGURATION menu, which also includes a submenu. The third is the DIAGNOSTIC menu. All three menu trees can be accessed by pressing the up or down arrow key. When the modem is in the data state, there is one idle screen and other data state status screens in Non-V.34 connection which can be accessed by pressing the left or right arrow key. ( There are nine and five data state status screens for V.34 and Non-V.34 mode display respectively.)

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. Values in one of the other screen displays may give much more detailed information than some of these status indicators; e.g., a data state screen means DCD is on, and an idle screen means DCD is off; SQ is better explained by the S/N ratio reading and the other impairment readings of data screen 2.
