COM Ports Won't Install At COM3 in Windows 2000

Symptom:

When I install my Digi product in Windows 2000, the new COM ports should start at 3 (or perhaps 5) but instead they start at a much higher number and I cannot rename them.

 

Cause:

• There was a Digi product previously installed in the system, and although the physical board was removed the adapter was not removed from Device Manager.

   

• A previously installed Digi product was not completely removed from the registry when the adapter was uninstalled.

   

  Solutions:

• The Digi adapter must be removed from Device Manager even though it no longer appears. Follow the instructions for removing phantom ports at the URL given below.

   

• To remove extraneous COM ports from the registry, follow the instructions given for removing phantom ports on the URL given below.
