Windows Millenium Only!
I just rec'd an Email from Dell stating this is an updated Driver for my old Dell Optiplex GX1. The actual modem chip is US Robotics D172A4PJ92 / 1.016.1067. Board says that the modem is a US Robotics Sportster 0467.
Of course I don't need to mention that neither Dell nor US Robotics lists anything for a Sportster "0467".
I only rec'd this because I registered with Dell. Here's a link
