I have installed both a PCI modem and an ISA modem in this computer. Both times I try to dial in I get this error msg.<br>Error 630: The computer is not recieving a response from the modem. Check that the modem is plugged in and if necessary, turn the modem off and then turn it back on again.<br>the computer is a pentium 200Mhz Aopen brand. Does any one know how to straighen this out?
