Appendix C – Flash Wizard
Your modem is controlled by semi-permanent software, called firmware, which is stored in flash memory.
Firmware is nonvolatile; that is, it remains stored in memory when the modem is turned off. However,
either the manufacturer or the user can change the firmware as bugs are repaired or new features are
added.
Multi-Tech System’s Flash Wizard utility can be used in the Windows operating system to update (flash)
your modem’s firmware.
The Flash Wizard utility is available on the MultiMobile CD or can be downloaded from Multi-Tech’s Web
site.

Upgrade Procedures
Overview
The upgrade (flash) procedure for the Windows operating system consists of the following steps, which
are described in greater detail later in the chapter:
1. Identify the modem’s model number and firmware version.
2. Identify the current version of the firmware from the Multi-Tech Web site. If your modem already has
the current firmware, there is no need to update it.
3. Download the upgrade (.HEX) file for your modem.
4. Install the Flash Wizard.
5. Extract the firmware upgrade (.HEX) file.
6. Document and clear your stored parameters.
7. Upgrade the modem’s firmware.
8. Restore your parameters.
Step 1: Identify the Modem’s Model Number and Firmware Version
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. In Windows 95, Windows 98, Windows NT, or Windows 2000,
you may use HyperTerminal.
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. The modem should respond OK.
3. After the modem responds OK, type ATi and press Enter. Record your results. The model number
and firmware version should appear similar to that shown below.
