DUNS Error 692

DUNS Error 692 - Hardware failure in port or attached device.

This error can occur if your modem is not properly installed, or for an external modem if the power to the modem is turned off. Verify the modem installation by checking Control Panel->Modems - driver and diagnostic (more info). The error can also be caused by a bad or loose serial cable with external modems.

This error can also occur if you have any service that gives a non-standard dial-tone such as telco-provided voice mail. The error can be avoided by adding commas before the number to dial.

This error can occur with Windows NT 4.0 if HyperTerminal already has the port in use. See this MS KB 160188 article.

With Windows 2000 or XP if you have Quicken 2000 installed: The error can be caused by the Quicken Download Manager; Removing the modem and re-installing it may result in the modem working - for a single session. The permanent solution is to remove Quicken 2000, or disable the Quicken Download Manager. This Intuit article explains how to turn off the Quicken Download Manager. The problem is also discussed in this Dell Solutions KB Article. Also see this Delltalk message.
