I have a friend who owns a Compaq running Windows 98, 64 MB RAM with an AMD K-2 processor (I don't know what speed). His original modem is a Rockwell HCF 56K PCI modem. It only connected at 26,400 so I gave him a Best Data 56K Mack II PCI modem. He installed it and now neither modem will work. When trying to connect to his ISP an error message comes up "Error 630: the computer is not receiving a response from the modem. Check that the modem is plugged in and turned on." We have uninstalled each modem several times and reinstalled each. We have tried them in both PCI slots. Device manager says the device is installed and working properly with no conflicts but we continually get this Error 630 message. We tried dialing a number using Hyperterminal and get the same message. The Best Data modem worked in two other computers. Are we missing something simple or does anyone have any ideas of something to try? TIA.
