as promised, the treasure trove of US Robotics dialup ISP software is now available on IA. Please note that while I've done my best to describe the software, none of it has been tested. If you're planning on doing something like firmware upgrades, be 100% sure it's the right equipment and firmware.
and if you're one of those lucky 9 people that has a USR Total Control device, i'd love to hear your results.
