What is it looking for (or discarding)?  I'm not sure this
is the right
way to do it..  normally you look for a service class which
is a specified
number (look for some of these defined in
/usr/include/sdp.h)

I think you may be looking for 'Serial Port' profile.

I think it is just a SDP_STRING that you have to parse for
that?
