The first link you posted is valid still, it uses the Dusky Device via a script and should operate as described.
The second link is from work I did along with @maybeoneday, I never completed to its end. The template I designed got trashed when my sqlCVS checkin didn't happen in a timely manner and device numbers crossed paths I ended up screwing up someone else's template. I had the device operational and plug and play but not packaged correctly. I should get back to this and complete it.
