So I wrote the test dissector and it showes up in the Enable Protocols

"Decode as", this menu item is grayed out, so I can't use it.
Here is the code of my first test:
-- trivial protocol example
-- declare our protocol
mpic_proto = Proto("mpic485","MPIC 485 bus protocol")
-- local packet_table = DissectorTable.get("packet")
-- packet_table:add(packet.USER15,mpic_proto)
Hi Christian,
the following Lua code
local wtap_encap_table = DissectorTable.get("wtap_encap")
wtap_encap_table:add(wtap.USER15, mpic_proto)
combined with text2pcap -l 162 is probably the easiest way
to use your Lua dissector for your text file packet data.
Regards,
Reinhard

Thanks Reinhard for your answer, but I tried the same already with the
K12-type text input, which worked fine in principle.
My problem is, that I would like to use an own link-layer type protocol.
But I played around al little bit and it seems, that I HAVE to enable
the "ethernet" Protocol do do anything with the data. Is that true?
Is it somehow possible to register an own link-layer protocol as a first
dissector? I would like to have sometthing like:
link-layer: pass data to i-layer
internet-layer: 1-4 byte dest and src adresses
transport-layer: port byte
application-layer: time,ftp,string,system... (all proprietary)
Hmm, difficult to describe.
Thanks and greetings
