Error 630: The modem is busy or not responding | The computer is not receiving a response from the modem | The port was disconnected due to hardware failure | The modem is not installed correctly.
Error 692: Hardware failure in port or attached device

This problem is something that ACD.net cannot assist with. The following troubleshooting steps are provided as-is. When receiving this error it is often best to contact whomever would normally support your computer.

Make sure the modem is physically installed properly in the computer. This would involve opening your computer and visually inspecting the cards plugged into the interface slots to ensure the modem is properly seated in its slot. It is strongly recommended that you ground yourself by touching the metal of the case before touching any components inside the computer.

Make sure the correct modem is specified in your Dial-up Networking connection. As with Error 602 and Error 633, sometimes when a modem is changed in the computer the old modem is not removed and the dial-up networking connection updated and told to connect using the new modem--Windows can't tell the modem to pick up and dial if it's trying to talk to the wrong modem! Follow these steps to make sure the modem you're using is the correct one.

Make sure Windows can communicate with your modem at the basic level. Once you know which modem your computer is trying to use for the connection, you will go into your modems settings in Windows to ensure that modem does in fact exist and Windows can communicate with it. Click on your version of Windows for instructions on how to do this:

Contact your computer support technician. If all else fails (or if this just seems like too much for you to take on yourself), you should contact whomever would support your computer. It could be that the modem has physically failed and needs to be replaced.
