the problem is that the tester don't sends a PN CMD (btw is this really
allowed?) and so we use RFCOMM_MAX_CREDITS at two points (once for the
session and for every DLC). If the PN CMD is present and shows us a 1.0b
device we set credits to zero and don't make use of credit based flow
control. It seems that the default value of credits must be zero and not
RFCOMM_MAX_CREDITS.
Regards
Marcel
