I'm working with a new bluetooth device that provides serial port emulation. I am working on automatic pairing and unpairing code and getting the serial port to show up, via API calls. This post was very helpful, but http://stackoverflow.com/questions/906454/accessing-bluetooth-virtual-com-port-on-windows-without-manual-pairing/909990#909990 Only 1 of the two serial ports show up. When pair manually in Windows bluetooth control panel, two show up. I can also manually setup the second port after automatically pairing and register the first. What can I do API-wise to get that second port automatically registered?
