Hi Sean,

Let me try to answer your questions, and let me know if you need more
detail.

1. The Microsoft stack that shipped with Windows XP SP2 does not provide a
L2Cap programming interface. The Windows sockets interface only provides
access to the RFCOMM layer and SDP functionality. The Windows Bluetooth
socket interface is described in detail on the msdn documentation
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/bluetooth/
bluetooth/windows_sockets_support_for_bluetooth.asp)

The Windows XP SP2 Bluetooth stack does have virtual COM support, but I
don't think this is what you're asking about. I probably need more detail
on what you're trying to do before I'll be able to accurately answer if /
how the Windows XP SP2 Bluetooth stack works with your product.

2. The Windows Bluetooth socket interface has many similarities to the WinCE
Bluetooth socket interfaces, but there are differences (e.g. the Blob
structure used for SDP is different between Windows XP and Windows CE). In
general, the Windows and Windows CE Bluetooth support targeted different end
user scenarios that were most applicable to their operating environment and
thus do not necessarily implement the same parts of the Bluetooth spec. If
you need more details on the WinCE Bluetooth support, you might want to try
one of the Windows CE newsgroups. I only have a limited experience with
Windows CE.

3. At this time, there are not any plans for Microsoft to support Bluetooth
under Windows 2000. However, it's possible that a 3rd party may develop (or
perhaps already has developed) Bluetooth support for Windows 2000.

4. The Windows XP SP2 Microsoft stack was developed at Microsoft.

I hope this answers some of your questions. Again let me know if you need
more details.

Good luck!
