Michael, Erwin, thank you for your help.
Should I use packet_sua.c as an example or is there a better example (m3ua
etc) available for my scenario?
Also, since the protocol I am trying to write the dissector for is not a
standard protocol, the payload of SCTP sometimes ends being interpreted as
m3ua (per the current display on ethereal 9.11). Will this cause any
problems?
Best Regards,
Sal
