bluetooth db9 adapter - one comm port after another

I snagged a socket bluetooth db9 serial adapter, which allows me some
valuable flexibility in doing some wireless lab communications with our
hardware over hyperterminal.

I've been having some trouble initiating the wireless link. I'm using
the built in windows XP sp2 bluetooth support rather than the drivers
that come with my dlink DBT-120 bluetooth adapter.

I've tried removing the socket adapter from my bluetooth devices
control panel and re-adding it, and that seems to get the connection
back, but each time I did that, it jumped up two comm ports.. Was comm
5 and 6, after removing and re-dececting it then takes comm 7 and 8.
How do I tell XP to release my comm ports that this thing is reserving
and then abandoning after I re-add?

Also, since I have need to do flash memory firmware updates over
bluetooth, is there increased error redundancy checking I can use to
decrease the chance of writing bad data from wireless tranmission
errors? I haven't had any problems with that yet and would prefer to
keep things that way.


what sort of settings do I want on the socket adapter? should it
initiate sessions or accept sessions? I assume either way should work
since I'm just trying to open a hyperterminal window to the thing.
