Hi Anton

    it seems a problem caused by a bad design of the BT serial port. Have you tried 
to contact the manufacturer to ask for explanations? In my opinion, you don't have many
chances to resolve the problem with the standard API. If the supplier can furnish you the
access to a deepest layer, for example with a specific DLL, maybe you can have more
control upon the process to open a port.
