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.
