after flashing. After you have recorded them, send the AT&F command to reset the modem to clear the stored -
parameters.
1. Run your favorite terminal program, such as HyperTerminal.
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&F and press Enter to clear your stored parameters and reset your modem to factory default.
5. Close the terminal program.
Upgrading the Modem’s Firmware
Warning: Never install an older version of firmware over a newer version. This destroys the flash PROM! If
the flash PROM is destroyed, the modem must be sent in for repair.
1. Click Start | Programs | Flash Wizard to launch the Flash Wizard. The Identifying Devices dialog box is
displayed as Flash Wizard locates and identifies the devices connected to your system.
Note: If the message ERROR: No valid devices detected is displayed, verify that the modem is turned on
and that all cables are correctly and securely attached.
2. Select the modem to be upgraded, and then click Next.
3. Select the port to be upgraded and the appropriate .HEX file, and then click Next.
Note: Do not use FLASHLDR.HEX. This file is used internally by Flash Wizard.
