Appendix E: Upgrading the Modem
Introduction
Your modem is controlled by semi-permanent software, called
firmware
, that is
stored in flash memory. Firmware is nonvolatile; that is, it remains stored in memo-
ry when the modem is turned off. However, it can be changed by either the manu-
facturer 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 great-
er 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 upgrade files from the file you downloaded.
5. Document your stored parameters.
6. Upgrade the modem’s firmware.
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 you should update it.
1. Run your favorite terminal program. If you are using Windows 95, 98, or NT 4.0,
you can use HyperTerminal. If you are using Windows 3.11, you can use Win-
dows Terminal.
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
ENTER.
3. Now type
ATI3
and record your results. The firmware version should appear
first in the results, similar to the following:
V2.210-V90_2M_DLS
