I think the problem with the other approach (I also tried it) was that
the underlaying frame size is different if you connect through a TTY. I
stuck it at 330 bytes which is a DH5 minus protocol overhead.

The test files 01, 03, 05 don't work for me.

Do you also use the Aiptek or the BlueTake one. The Aiptek is very old
and maybe the decoder in my headphone has a bug.
