Introduction

Like any modem, your Multi-Tech modem operates only under the control of a communication program, such as the Trio DataFax program included with the modem. It also operates under other general-purpose data communication pro- grams, such as Windows Terminal and HyperTerminal. For information on how to use the modem with the communication program of your choice, please refer to the program’s documentation.

Modem Configuration

Your modem normally is configured through Windows or through the communica- tion program you are using. The default settings work best for most purposes. See “Step 3: Install and Configure Your Software” in Chapter 2 for help in setting up your communication program.

You also can configure your modem either through the front panel or by sending AT commands to the modem. This chapter describes how to configure it using the front panel. To configure it using AT commands, see Chapter 4.

LED Indicators

The MT5600BA/BL has six LED indicators on the front panel that indicate status and activity:

Receive Data. The RD indicator flashes when the modem is receiving data.

Transmit Data. The TD indicator flashes when the modem is transmitting data.

Carrier Detect. The CD indicator lights when the modem detects a valid carrier signal from another modem. It is on when the modem is communicating with the other modem, and off when the link is broken.

Off-Hook.The OH indicator lights when the modem is off-hook, which occurs when the modem is dialing, online, or answering a call. The LED flashes when the modem pulse-dials.
