1.2.1 Software – Flash Upgrading
The internal software is powerful and flexible, permitting storage and retrieval of up to 10 different
modem configurations. The modem uses ‘flash memory’ technology internally, and new firmware
can be uploaded to the unit from an external PC. This simplifies software upgrading, and updates
can now be sent via the Internet, e-mail, or on disk. The upgrade can be performed without opening
the unit by simply connecting either to the modem Ethernet port or the USB1.1 port
