I think this is correct, however, for a little bit more feedback:
So far I have others that have used this pen in Windows and they got
it working by renaming the virtual serial port to the expected name
(using the widcom stack). If the serial ports are exported as services
then you're definately spot on (I guess I have some reading to do on
the SDP for bluetooth).

Please forgive me for being confusing, I have had very little
information to begin with. As for implementing a RFCOMM server and
exporting it do I build it on top of existing bluez source code or can
I hook the utility programs rfcomm together with the sdptool somehow?
Or is this better suited for the development list?

Thanks for the reply
Regards
