my computer is a compaq presario 5900t, windows 98 se, pentium 3- 733, 384 RAM, modem is conexant 56k pci fax modem. my problem is that my hard drive went bad, and i installed a new one. i can get everything to work, except the modem. i receive the message: Could not detect modem. It may be turned off, in use, or not installed properly. I have removed it from device manager and tried plug and play several times, and installed drivers. it finds the hardware, but it still doesn't connect. the isp number is correct, as i'm using it on another computer. i also got a different error message once also. it was "cannot read port name from regsistry". compaq suggested reinstalling COM ports and Modem drivers. I followed their instructions, but that doesn't help. any suggestion????? (by the way, this is a great forum. very helpful in the past)
