i haven't used the serial io_service yet, but i guess it uses a file 
handle created by CreateFile() on Windows 
(http://lists.boost.org/mailman/options.cgi/boost-users/mailing-lists%40michi7x7.de) 
and
on Linux and MacOS surely a file handle to /dev/tty... is used (because 
these FIFOs can be opened using fopen()). native() returns a file-handle 
then.

Because I haven't yet used such functionality, i don't know of any 
library that wraps it, but you might contribute one to bost ;)

On note to the bluetooth-question: I just found parts of a 
bluetooth-device-api on MSDN, I'm not sure if Windows can wrap them to 
COM-Devices. But I'm quite sure, that there are no problems if they can 
be accessed using "COMXX".

PS: usually you use a COM-Port to send data to one device without 
thinking about how the data gets transfered. If you need to set loads of 
parameters though, I'm not sure if "COMXX" or /dev/tty... is the right 
approach for you.

PPS: of course you can set parameters like baud-rate or arity using 
boost.asio
