--- Comment #7 from Martin Mathieson <martin.r.mathieson@xxxxxxxxxxxxxx>  2008-03-13 11:36:25 GMT ---
There is already a SABP dissector.  I know its been tested on test files that
didn't have proper transport details.

As a test, I added the following lines to proto_reg_handoff_sabp():

    sabp_handle = find_dissector("sabp");
    dissector_add_handle("tcp.port", sabp_handle);

I was then able to right-click and Decode-as SABP. I've pasted the decode I got
below.

Better, though, would be to register the well-known port.  Iana says its 3452
for TCP and UDP, so I also added:

    dissector_add("tcp.port", 3452, sabp_handle);
    dissector_add("udp.port", 3452, sabp_handle);

This also seems to work.

I'll try to check in a change later today, but this dissector is generated from
a template file, and I'm not sure if I have the correct tools to run the
generation script at the moment...
