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

Step 6: Upgrade the Modem’s Firmware
Before you begin the following procedure, read the README.TXT file extracted from the upgrade
archive file. Note the file name for the new firmware (example: ARQG125A.HEX). Also, if you are using
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 ENTER.
