Multiple Events Appear for Intelligent Digiboard Adapters

After you upgrade to Windows NT version 3.5 with any of the Intelligent Digiboard adapters, more than one of the following events may appear in the Event Viewer:


where: <a> is order number of installed adapters in Windows NT (usually 2 if a network adapter was installed first on this computer) <b> is the line number used on the Digiboard adapter (usually 1) <c> is the concentrator number used on the Digiboard adapter (usually 1) <d> is the number of each port configured on the Digiboard adapter.

The ntxall subkey in the Windows NT Registry should reside under the Services subkey of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet for all intelligent Digiboard adapters. Any subkeys residing under the Parameters subkey of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Serial are port configurations for non-intelligent Digiboard adapters and any additional communication ports. This problem occurs after the upgrade process where a copy of the ntxall subkey tree was placed under the Parameters subkey.

To prevent these events from appearing in the Event Viewer, modify the Windows NT Registry.

1. Start REGEDT32.EXE and locate the following Registry subkey:
   
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet \Services\Serial\Parameters
2. Remove all subkeys below and including ntxall<a>.
3. Exit the Registry Editor.
4. Shut down and restart Windows NT.
