My software works well with Vb6 and VB.net and Bluethoot. I use MSCOMM32.OCX. Yesterday I bought a bluethoot of SENA and am having trouble reading from com port. Microsoft says the problem is in the driver's key Bluethoot that does not end the communication. It remains in suspention mode The error is Error 8020. Error reading the communication device. Is there a remedy? Thanks-
