Communication programs designed for DOS and other operating systems, however, may need to be manually configured to work with your modem.
Chapter 3 Operation
MultiModemZBA-V-V92 User Guide 3 Operation Chapter 3 - Operation Your Multi-Tech modem operates under the control of a communication program, such as the PhoneTools program included with the modem. It also can operate under other general-purpose data communication programs, such as Windows HyperTerminal. For information on how to use the modem with the communication program of your choice, please refer to the program’s documentation. Front Panel Figure 3-1.
MultiModemZBA-V-V92 User Guide 3 Operation OH 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. TR Terminal Ready. The TR indicator lights when a communications program is using the modem. It means the modem is ready for an outgoing or incoming call. It goes off when the communications program disconnects the serial port. When it goes off, a connected modem will also disconnect.
MultiModemZBA-V-V92 User Guide 3 Operation Leased Line Operation The MultiModemZBA-V-V92 modem can be used on a two-wire leased line. A leased line is a private, permanent, telephone connection between two points. Unlike normal dialup connections, a leased line is always active. The modems automatically connect when they are attached to the line and are turned on.
MultiModemZBA-V-V92 User Guide 3 Operation V.92 Operation Because the V.92 protocol is new and still largely unsupported by central servers, some features are disabled by default in the initial release of the MT5634ZBA-V-V92 modem. This section describes the status of the V.92 features in the initial release. Please note that the V.92 special features require connection to a V.92-capable server. General. The V.92 protocol is enabled by default. If the MultiModemZBA-V-V92 detects another V.
MultiModemZBA-V-V92 User Guide 3 Operation Dial-Up Networking Before you can connect to the Internet, you must set up a remote-node client program on your computer. The Windows version is called Dial-Up Networking. Dial-Up Networking establishes your connection to the ISP’s server, which is the shared computer that manages calls from clients (your computer) to the Internet. Most, if not all, Windows browsers start Dial-Up Networking automatically when you open them.

Chapter 8 Solving Problems
MultiModemZBA-V-V92 User Guide 8 Solving Problems Chapter 8 - Solving Problems Your modem was thoroughly tested at the factory before it was shipped. If you are unable to make a successful connection, or if you experience data loss or garbled characters during your connection, it is possible that the modem is defective. However, it is more likely that the source of your problem lies elsewhere.
MultiModemZBA-V-V92 User Guide 8 Solving Problems The Modem Does Not Respond to Commands Ö Make sure the modem is plugged in and turned on. (See “None of the Indicators Light.”) Ö Make sure you are issuing the modem commands from data communication software, either manually in terminal mode or automatically by configuring the software. (You cannot send commands to the modem from the DOS prompt.) Ö Make sure you are in terminal mode in your data communication program, then type AT and press ENTER.
MultiModemZBA-V-V92 User Guide 8 Solving Problems Ö The serial port might be defective. If you have another serial port, install the modem on it, change the COM port setting in your software, and try again. Ö The modem might have a problem beyond the scope of this user guide. If you have another Multi-Tech modem, try swapping modems. If the problem goes away, call Technical Support for assistance (see Appendix D).
MultiModemZBA-V-V92 User Guide 8 Solving Problems Ö If the modem reports NO ANSWER, the other system has failed to go off-hook, or you might have dialed a wrong number. Check the number. Ö If the modem reports NO CARRIER, the phone was answered at the other end, but no connection was made. You might have dialed a wrong number, and a person answered instead of a computer, or you might have dialed the correct number but the other computer or software was turned off or faulty.
MultiModemZBA-V-V92 User Guide 8 Solving Problems The Modem Cannot Connect When Answering Ö The default DTR Control command (&D2) inhibits autoanswer. To enable autoanswer, change DTR Control to &D0, and make sure &Q0, &Q5, or &Q6 is also set. For more information, see the &D command in Chapter 4. For information on changing the modem’s default configuration, see “Step 6: Install and Configure Your Software” in Chapter 2. Ö Autoanswer might be disabled.
MultiModemZBA-V-V92 User Guide 8 Solving Problems There Are Garbage Characters on the Monitor Ö Your computer and the remote computer might be set to different word lengths, stop bits, or parities. If you have connected at 8-N-1, try changing to 7-E-1, or vice-versa, using your communication software. Ö You might be experiencing line noise. Enable error correction, if it is disabled, or hang up and call again; you might get a better connection the second time.
