Step 4: Extract the Upgrade Files
1. Move downloaded upgrade file to a temporary directory or folder on
your hard disk.
2. The file is a self-extracting archive. Extract files by typing the upgrade
file name in DOS or double-clicking it in Windows. The extracted files
include a .HEX file, which contains upgrade data, and one flash
program each for DOS, Windows 3.1/95, 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 any stored parameters. You should also record the
parameters that currently are stored in your modem so you can reprogram
it after flashing.
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&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.
5. Close the terminal program.
Step 6: Upgrade the Modem’s Firmware
Use one of the flash programs that you extracted to upgrade your modem.
There are three flash programs: DOSFLASH.ZIP for DOS or Windows 3.1,
FLASHWIN for Windows 3.1 or Windows 95, and FLASHNT for
Windows 95 or Windows NT 4.0.
