Appendix E: Upgrading the Modem
Introduction
Your modem is controlled by semi-permanent software, called firmware , which is
stored in flash memory. Firmware is nonvolatile; that is, it remains stored in memory
when the modem is turned off. However, it can be changed by either the manufac-
turer or the user as bugs are fixed or new features are added.
Since the firmware in your modem is stored in flash memory, you can upgrade it
yourself in a few minutes by using the following procedures.
Upgrade Overview
The upgrade procedure consists of the following steps, which are described in greater
detail in the following sections.
1. Identify the model number and firmware version of your modem.
2. Identify the current version of the firmware at the Multi-Tech Web site or BBS. If
your modem already has the current firmware, there is no need to update it.
3. Download the upgrade file for your modem.
4. Extract the firmware .HEX file and the appropriate flash upgrade program from
the file you downloaded.
5. Document and clear your stored parameters.
6. Upgrade the modem’s firmware using the .HEX file and the flash upgrade
program.
7. Restore your parameters.
Step 1: Identify the Modem Firmware
You must know the model number and firmware version of your Multi-Tech modem
to know whether or not you should update it.
1. Run your favorite terminal program. If you are using Windows 95, Windows 98,
Windows NT, or Windows 2000, you can use HyperTerminal.
2. In the program’s terminal window, type
AT&F
. Even if you cannot see the
AT&F
command on your screen, be sure to type it completely, and then press
E
NTER
. If the modem does not respond with OK , repeat the
AT&F
command.
3. Now type
ATI3
, press E
NTER
, and record your results. The firmware version
should appear first in the response, which should look similar to the following:
