Dirk,
Is it possible to get a patch for unsigned conversion ?
I would prefer that to additional records as there are many of them.
( I am converting an existing driver to stream)

Please let me know.
I looked at the code, I think it is just a matter of changing signed
char to unsigned char and adding a new flag in the code of the
converter.

Regards,
