I am doing an upgrade from a 233 to an AMD K6-2 400mhz motherboard. The modem is a Diamond multimedia and was working fine in the 233 with Supramax 56i PCI setting on COM 2. I have installed the modem into the new computer but I keep getting the message that it can't communicate with the modem.The new port is COM 1 (COM 2 is for the mouse) Windows seems to think that the modem is correctly installed except if I click on "more details" on the modem setting I get the message "cannot read port name from registry". Also,on boot up, Windows detects new hardware for the PCI serial controller but can't find a device driver for it. Is this message related?. I have tried reseating the modem and also a different PCI slot. On boot up, the PCI devices listing that scrolls by doesn't include a modem.
