Before these were applied to my model Megahertz XJ5560 56k PC Card modem, Windows was using its "Generic PCMCIA Modem" driver. First I flashed the modem with both updaters, then updated the modem driver in the Windows Device Manager control panel. My connect speed has increased dramatically.

Support for this and other older Megahertz, US Robotics and 3Com PCMCIA modem has been discontinued. Drivers can be found at
