We have had perennial problems with Hiper modems suddenly not responding. Every other day I get a random modem or two that stops responding per card. Rarely a software reset will return the modem to service. Usually, I wait a week until I have several, then do a hardware reset. This returns most to service, except the occasional bad channel. I am running 2.0.60 per 3com. I am not using 2.0.51 as I am under the impression it is for a newer hardware version than we own. I have not yet upgraded the Hiperarc software to the latest-I am waiting for the next time I do aforementioned hardware resets. (Day traders get very upset if they get booted : ). Suggestions and questions? Thanks Christopher Berry rof.net Web Design and Technical Support (970) 945-4920 x17
