    One thing I've noticed with some recent Megahertz and 3Com PCMCIA modem cards when using NT4 and connecting to a Com Total Control box. If you disable PPP LCP extentions it seems to help get and stay connected.

  • 3Com also owns Megahertz and is separating the US Robotics line off from regular 3Com products.
