What modems are supported?
Southwestern Bell Internet Services has extensively tested its service with modems from many different manufacturers. Most recent Hayes-compatible modems should work with our service. We have found that some modems are incompatible with our Netscape software, particularly modems that require custom software-based drivers. Many modems based on the Rockwell Protocol Interface chipset with a Windows 3.1 system will not work properly because of the reliance on proprietary software drivers.
