Arguments: port topic item value
If send-request was called with a link type of :hot or :warm, then this generic function will be invoked whenever the server tells us that the value for the requested item has changed. You may write methods on this generic function to handle these change notifications however it is appropriate for your application.
If the send-request link was :hot, then
value will be the DDE server's new value for this topic and item, as
converted by the convert-returned-dde-buffer method
for this DDE port. If the link was :warm, then value will be nil, and send-request (with a :cold link)
must then be called if the application needs to know the new value,
rather than the simple fact that a change to this topic and item has
occurred.
