Upgrading Your 3Com U.S. Robotics Modem
=======================================

Make sure your modem is offline before attempting the upgrade.

 1. Run the UPGRADE.EXE program located in the C:\3Com directory.

 2. The program will locate the U.S. Robotics x2 modem in your system.
    When prompted, click the FLASH! button to perform the upgrade.

 3. Once your modem is successfully upgraded, click the Quit button.

 4. Shutdown and restart Windows 95/NT.

 5. If your modem is set to Plug and Play mode (the default), Windows will
    identify your modem as a new device. When prompted for a device driver,
    indicate that you have a manufacturer's disk and instruct Windows to look
    in the C:\3Com directory. Repeat when prompted for a serial wave driver.

 6. If your modem is jumpered to a particular IRQ/COMM setting, you need to
    remove the previous modem configuration and create a new one. Open the
    Control Panel and start the Modems applet. Remove the existing modem,
    then click the Add button to install your "new" modem. When prompted
    for the driver disk, indicate that you have a manufacturer's disk and
    instruct Windows to look in the C:\3Com directory.

If the UPGRADE program doesn't find your modem, make sure you downloaded the
correct upgrade program for your modem. Double-check the firmware date in
your modem with the list on the 3Com's 56K modem upgrade page.
