Step 6: Upgrade the Modem’s Firmware
Before you begin the following procedure, read the README.TXT file extracted from the upgrade

Windows NT, you must disable Windows RAS and Microsoft Fax Service before upgrading the
modem’s firmware. To disable RAS and your Fax service, Click
Start

Settings
|
Control Panel
, and
then double-click
Services
. Select
Remote Access Server
, and then click
the
Startup
button.
Select
Manual
as the startup type, and then click
OK
. Do the same for any fax service.
WARNING:
Never install an older version of firmware over a newer version. Doing
this WILL DESTROY THE FLASH PROM! If the flash PROM is destroyed, the mo-
dem must be sent in for repair.
1. Run Flash Wizard by double-clicking its icon or file name, or by selecting it from the Start
menu. The program begins by identifying devices attached to your computer.
2. Select the modem to be upgraded, and then click
Next
to proceed.
3. Select the port to be upgraded from the
Port
list, select the appropriate .HEX file from the
Hex
File
list, and then click
Next
to continue.
Note:
Do not use FLASHLDR.HEX. This file is used internally by Flash Wizard.
4. The
Progress
dialog box now displays the progress of the upgrade.
Caution:
Any disruption of the program during this stage of the upgrade can
cause your modem to become inoperable. Wait for the
Next
button to become
active before proceeding.
5. When the flash upgrade is complete, the message
Programming Complete
appears. Click
Next
to
continue.
6. The
Results
dialog box appears next. Click
Finish
to exit Flash Wizard.
Note:
If you are using Windows NT, be certain to enable RAS and your fax ser-
vice when the operating system restarts.
Step 7: Restore Your Parameters
Your modem has been updated. You can now open your terminal program to reprogram your modem
parameters or to confirm the update by typing
ATI
in the terminal window and pressing E
NTER
