Step 1: Identify Your Modem‘s Number and Firmware
You must know the model number and firmware version of your Mult-Tech modem to know whether
or not you should update it.
1. Run your favorite terminal program. If you are using Windows 95 or above, you can use
Windows 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. If the modem does not respond
with OK, repeat the AT&F command.
3. Now type ATI, press Enter. The model number and firware version should appear. Record these
results.
Step 2: Indentify the Current Firware Version
1. Using your favorite Web browser, go to http://www.multitech.com/support/MultiModemZBA/
firmware.asp
2. Scroll down to your modem model number.
3. Look at the firmware version number for your modem.
4. If the firmware version number matches the firmware version number found in Step 1, you have
the current firmware version and do not need to update.
5. If the firmware version is greater than the one found in Step 1, your modem has an older version
of firmware. Continue with Step 6.
Warning: The first digit of the new firmware must match the first digit of the old firmware or the
modem may not work properly. If your current version is 4.16, replace it only with 4.xx, not 6.xx.

the procedure in “Step 2: Identify the Current Firmware.”

folder on your hard disk.

download it, and save it in the same folder.
