3.2.4.1.1 Sending a CPMCiStateInOut Request
Typically, the higher layer asks the protocol client to send a CPMCiStateInOut message when it requires information on indexing services on the server.
When requested to send this message, the client MUST do the following:
Send a CPMCiStateInOut message, as specified in section 2.2.3.1, to the server.
Wait to receive a CPMCiStateInOut message from the server, silently discarding all other messages.
Report back the value of the _status field of the response (and, if it was successful, the informational structure) to the higher layer.
