Installed this modem on a PIII mainboard after the Lucent Winmodem was killed by lightning. Modem works fine until you shut down or reboot the system. After a reboot, when I go to modem diagnostics, it says the com port is already open. If you remove and reinstall the modem it will work fine again until you reboot or shutdown. Anybody got any ideas what's going on here? <img src="confused.gif" border="0">
