29 Most transactions involve a topic name and an item name (choose these
30 as befits your application).
34 - ask the server to execute commands (data) associated with a topic
35 - request data from server by topic and item
36 - poke data into the server
37 - ask the server to start an advice loop on topic/item
38 - ask the server to stop an advice loop
42 - respond to execute, request, poke and advice start/stop
43 - send advise data to client
45 Note that this limits the server in the ways it can send data to the
46 client, i.e. it can't send unsolicited information.
