After installing the modem, It shows that I have a HSP56 MicroModem installed on Comm Port 1. When I go to phone and Modem Options and click on Properties, then Diagnostic and Query Modem I'm getting this message back" open comm: the port that the modem is attached to could not be opened. This may be the result of a hardware conflict. Check the device manager to verify all devices are functional." It will let me query the MicroModem , but it will not query the new modem ( that's when I get the message above ). I have reseated the modem 3 times. I have deleted the software and re-installed the driveres. I have checked the device manager for conflicts and there was no hardware conflicts. The modem is brand new out of the box. Its a Trendnet PCIV92A HIGHSPEED internal PCI data/fax/voice modem thats going a Athlon X1900 computer that's using WinXP pro operation system, I have 512 meg of ram. Please help..what am I doing wrong.
