Thanks for the responses; they have helped, albeit in an indirect way. Unfortunately I can’t supply the details, however our development team have now told me they can build Ethereal again with changes implemented to produce the necessary decode. I will update with more details when this is done.

 

Regards

Which udp port are you using? How are the frame delimiters protected?
Byte stuffing? One frame per UDP packet?
