This driver flashes your modem to the v90 standard. This file is more than likely only gonna work on the Practical Peripherals PM K56 5676US internal modem. If you don't have the 5676 model, you can still try it. It will not flash your modem if your modem does not support it. After I upgraded my modem, I went from 28.8 to 50k and higher.
