Appendix B. FLASH UPGRADING
The modem eliminates the need for updating firmware by physically replacing EPROMs.
Instead, the modem uses 'flash memory' technology internally, and new firmware can be
uploaded to the unit from an external PC, as follows:
This makes software upgrading very simple, 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 the modem to the USB or Ethernet port of a computer.

The current base modem M&C version can be viewed at the top-level menu
of the front panel display (press "CLR" button several times to view).
•
The firmware information can be found within the <Util > <Firmware >
<Info> <Image#1, Image#2 > menu tree.
•
Using serial remote control, the firmware revision levels can be queried with
the <0/SWR? Command (Abbreviated) Or <0/FRW? Command (Detailed).
Using Windows: Select File ! New ! Folder ! and rename the New Folder
to "temp" or another convenient and unused name.
Assuming "temp" works, you should now have a "c:\temp" folder created.
Note: The c: is the drive letter used in this example. Any valid writable drive
letter can be used.
