forget about that. I was confused and thought that you wanna connect
from the PC to your phone,

If you put it into a tar then name it this way ;)

The string "Handy!" goes over the connection and right after that the
Linux side closes the connection. Maybe that is the problem or it is the
credit based flow control on the phone. I don't see any CFC problem, but
I also didn't wrote the Bluetooth stack on the phone. I think it is a
good idea to add a sleep(1) before you close the connection.

Some other information might be handy. What kernel do you use and what
do you use as server on the Linux side? What kind of phone is this?

Regards

Marcel
