Terminal Ready. The TR indicator lights when a communication program is using the modem. It means the modem is ready for an outgoing or incoming call. It goes off when the communication program disconnects the serial port. When it goes off, a connected modem will disconnect.
Test Mode. The TM indicator lights when the modem is in test mode.
Liquid Crystal Display (LCD)
The MultiModemII’s backlit liquid crystal display (LCD) has two functions: to dis- play the current status of the modem and to display configuration menus, which are selected using the four pushbuttons on the front panel.
Option Selection
To select most configuration options, simply display the option in the LCD, and then press the Enter button to select it. An OPTION SET message appears to confirm the selection. To exit the OPTION SET message, press any button.
Some options, such as password options and phone number options, require you to enter a character string. To select a character, press the 〈⇓ and buttons. To go to the next character position, press the ◊ button. To backspace, press the ◊ button before selecting a character. To exit without saving, press the ◊ button several times. To save a character string, press the Enter button.
Menu Structure
The LCD menus have a tree structure with multiple trunks, limbs, branches, and twigs. For a schematic view, refer to the menu map on the next page.
Trunks are the major divisions of the menu tree. There are seven trunks: Status, Ba- sic Options, Advanced Options, Remote Configuration, Diagnostics, Phone Number Memory, and Caller ID. Use the 〈⇓ and buttons to move between trunks.
Limbs are subdivisions of trunks. Use the ◊ button to move from a trunk onto its first limb, and the 〈⇓ and buttons to move between limbs on the trunk.
Branches are subdivisions of limbs. Use the ◊ button to move from a limb onto its first branch, and the 〈⇓ and buttons to move between branches on the limb.
Twigs are status screens and options that are accessible only from branches. Use the
àbutton to move from a branch to its first status screen or option; then press the áß and à buttons to move between options, and press the Enter button to select an op- tion.
