Step 4: Extract the Upgrade Files

1.Move the downloaded upgrade file to a temporary directory or folder on your hard disk.

2.The file is a self-extracting archive. Extract the files by typing the upgrade file name in DOS or double-clicking it in Windows. The extracted files include a .HEX file, which contains the upgrade data, and one flash program each for DOS, Windows 3.1/95/98, and Windows NT.

Step 5: Clear Your Stored Paramenters

Before you flash your modem it is important that you issue the AT&W1Z command to it to clear out any stored parameters. You should also record the parameters that are currently stored in your modem so you can reprogram it after flashing.

2.In the program’s terminal window, type AT&V and press ENTER to list your modem’s current parameters.

3.Record your parameters by saving the screens and sending them to your printer.

4.Type AT&W1Z and press ENTER to clear your stored parameters and reset your modem to factory default.
