ModemModule Developer’s Guide

Introduction

Your ModemModule is controlled by semi-permanent firmware that is stored in flash memory. Firmware is nonvolatile; it remains stored in memory when the modem is turned off. However, it can be changed by either the manufacturer or the user as bugs are fixed or new features are added.

Since the firmware is stored in flash memory, you can upgrade it yourself in a few minutes by using the following procedures.

Upgrade Overview

The upgrade procedure consists of the following steps.

1.Identify the model number and firmware version of your modem.

2.Identify the current version of the firmware at the Multi-Tech Web site or BBS. If your modem already has the current firmware, there is no need to update it.

3.Download the upgrade file for your modem.

4.Extract the firmware .HEX file and appropriate flash upgrade program from the downloaded file.

5.Document and clear your stored parameters.

6.Upgrade the modem’s firmware using the .HEX file and the flash upgrade program.

7.Restore your parameters.

Step 1: Identify the Modem Firmware

You must know the model number and firmware version of your Multi-Tech modem to know whether you should update it.

1.Run your favorite terminal program. If you are using Windows 95/98 or Windows NT, you can use HyperTerminal. If you are using Windows 3.11, you can use Windows Terminal.

2.In the program’s terminal window, type AT&F. Even if you cannot see the AT&F command on your screen, be sure to type it completely and then press ENTER.

3.Type ATI and record your results. The model number and firmware version is displayed:

LT 33.6 MT3334SMI Serial Data/Fax/Voice Modem Version 4.16

Step 2: Identify the Current Firmware Version

Identify the current version of the firmware at the Multi-Tech Web site or BBS. If your modem already has the current firmware, there is no need to update it.

Multi-Tech Web Site

1.Using your favorite Web browser, go to http://www.multitech.com/support/firmware.htm.

2.Scroll down to the table with your modem model number (non-USA firmware must be obtained directly from the ftp site or BBS at this time).

3.Look at the Current Revision number for your modem.

4.If the Current Revision number matches the firmware version number found in Step 1, your modem has the current firmware version and does not need to be updated.

5.If the Current Revision number is larger than the firmware version number found in “Step 1: Identify the Modem Firmware,” your modem has an older firmware version. Continue with Step 3.
