Rockwell & PCTEL do not manufacture modems, they make the chipsets (the Integrated Circuits) that are used in many different modems, there are however differences in the way that different brands work.

Therefore before going any further you need to know WHO made your modem, to find out you need the FCC ID number!

This is usually located on the board or back panel:


You need the first three characters then check here in the FCC database to look it up.

* If you are located in the UK or Europe then check the BABT database.

Also read the Wanted Page for helpful tips.

Here is an example of Rockwell chipsets that are used in Aopen modems, but these may not work for you so be careful especially with firmware upgrades.
