Chapter 9 – Firmware Upgrade
Procedure
Introduction
Flash Upgrade Firmware
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 a Windows operating system to update (flash) your
modem’s firmware.
The Flash Wizard utility can be downloaded from Multi-Tech’s FTP site and is available on CD.

Upgrade Steps
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. In Windows 95, Windows 98, Windows ME, 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.
