I have installed a PCI v90 56k modem on a 486dx 4 machine. I went into the bios and disabled com2, then changed the I/O settings for the modem in the system properties. the modem worked fine once I did that. However the problems started when I rebooted the computer. Now it sees the modem but when I try to connect to the internet, dial-up networking says that there is no modem installed. When I go into the control panel and run a diagnostics on the modem it responds that the port is open. Any suggestions?

I've had a customer with the same problem.
It turned out to be the cable. So try a different cable and see how that goes

Check in BIOS you have explicit definitions for port COM1 and that COM2 is disabled. Try to play with "PNP OS Installed" setting in BIOS. Uninstall modem in Control Panel and let system finds it again. I had similar problem when tried several PCMCIImodem cards without reboot and didn't uninstall drivers after removing card.

Good luck.
