/*
* Mini-DDE implementation
Most transactions involve a topic name and an item name (choose these
as befits your application).
A client can:
- ask the server to execute commands (data) associated with a topic
- request data from server by topic and item
- poke data into the server
- ask the server to start an advice loop on topic/item
- ask the server to stop an advice loop
A server can:
- respond to execute, request, poke and advice start/stop
- send advise data to client
Note that this limits the server in the ways it can send data to the
client, i.e. it can't send unsolicited information.
