Ports and modems

By gold ·
I would like to know what Windows 95 means by the error: "Unable to open port". This error occurs when I attempt to test the modem on my user's PC. I have com ports 1 thru 4 available in Device Manager. I have de-installed the modem and re-installed it, hoping Windows would assign a port not in conflict. This PC is a Compaq Armada 1700 laptop

Reboot - go to BIOS Disable both COM ports.
Boot - Go to windows95/98 safe mode.
Go to Device Manager. Expand Modem and remove from device manager.
Reboot - Let windows find the modem and (presumably a PNP modem) if not make sure you set it for COM1 IRQ4 or COM2 IRQ3. Load drives. Test modem in Properties.
Does not work. Go to Registry Hkey_Local_Machine\Enum look any root which pertains to the modem., Delete that section only. First, however, make a back of the Registry.DAT file (hiddenfile in Windows folder) Use attrib to bring it down copy and use attrib to bring it up again.
Use Enum section is deleted reboot. Reload the drivers. Does not work. Go to the internet of the modem maker and get new drivers. And go back to the beginning and try again.
Good luck Harry

4: Disable Ports
5: Power down and reseat modem
6: Power up and let windows detect modem
7: Write down the IRQ settings

All the answers above are good, but there is one thing that I have ran into. The modem is bad. I have gotten this error msg when the modem will not hang up. P.S. winmodems are the worst at this.

Check to see that the port is enabled and has no conflict. use the my computer properties, device manager to view.

Make sure that the modem is pointing to the correct port, check this from the controll panel.

Try removing the ports and restart your machine.

Is your modem PCI? If it does, check the IRQ. Sometimes PCI modems select IRQ's 9 to 11, that setting don't work a lot of times. Check your motherboard BIOS. Is the modem IRQ set to 3 or 4 on the BIOS. Leave it that way. Change IRQ 3 to PCI/ISA PnP.Then change the IRQ where the modem is set to ISA. Save the changes to your BIOS and reboot the system.
Check now the device manager to if the modem is on IRQ 3. If not , try to change it manualy on the device manager. Repeat the process if necesary. Sometimes this takes a little to get it right.
