Vb.Net Bluetooth Serial Port

Hi All, I\'m doing some serial I/O in VB.NET for a project at work. I\'m new to VB.NET so I\'m not sure if I\'m doing this correctly. I need to determine what ports are free and which ones are in use. Presently, I try to open the port and if there\'s an error I know that port is not available.

I think there must be better way. See code below.

I got the same result with other software in the form of \'exception, access.\' , which works on direct serial port via USB converter. I can communicate with the Bluetooth device connected to an ATMEGA168PA from my android phone perfect, both ways.

Try TempPort.Open() Catch ex As UnauthorizedAccessException Return False End Try TempPort.Close() Return True End Function End Module.
