External (Serial/RS-232) Support Files

Please note the presence or absence of letters in the model numbers below when selecting files for your modem. An "L" in your modem's serial number indicates you have an Agere (Lucent) chipset. The absence of an "L" or the presence of an "C" indicates you have a Conexant (Rockwell) chipset. The modem's serial number is located under the barcode on the bottom label.

"x" is any integer from 0-9 in the following examples:

xxxx-Z3049-xx-xxL-xxxx uses an Agere chipset.
xxxx-Z3049-xx-xxC-xxxx uses a Conexant chipset.
xxxx-Z2949-xx-xx-xxxx uses a Conexant chipset.

Firmware updates for use with our Agere chipset-based modems will not work with our Conexant chipset-based modems, and vice versa.
