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 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 com- pletely and then press ENTER.

3.Now type ATI and record your results. The model number and firm- ware version should appear as shown below.

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.
