IMPORTANT: This article contains information about modifying the registry.

256986 Description of the Microsoft Windows Registry



CAUSE
The code for the Modem Sharing Service has a limitation in the number of characters that a configured serial comm port can be named. Some third party multi-port boards will name the ports with long descriptive names causing this behavior.



RESOLUTION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

Check in the documentation or with the vendor of the multi-port board and see if the ports can be installed with a custom name and install them with standared port names (ie: COM3, COM4, etc). If this is not an option the following procedure should correct the Modem Sharing Trap.

 Go to Start/Settings Control Panel Run the Services applet, click on Modem Sharing, Click Stop Start Registry Editor (Start/Run/Regedt32.exe). Navigate to the key HARDWARE\DEVICEMAP\SERIALCOMM. Highlight the SERIALCOMM folder. From the Edit pull down choose Save Key and back up this registry key in the event it must be restored.</li>  Locate the port name values for the multi-port board under the following key in the registry: <pre class="fixed_text">  HARDWARE\DEVICEMAP\SERIALCOMM </li> Double Click on the value to be edited, delete any characters except a description of COM# and click OK. For Example:

dgapci4Line1Concentrator1Port1:REG_SZ:COM3-PORT1 Change to Serial0:REG_SZ:COM1

Repeat this for all ports.</li> Quit Registry Editor.</li> In the Services Applet click on Start.</li> In Control Panel run the Modem Sharing applet to configure Modem sharing.</li></ol>

NOTE:The key value is limited to 7 characters total.
