Control Flow: Once the client has established a network connection with a server, the server must instantiate a new, empty, BasicEnrollmentManager implementation for this client, and must respond to the new client with a welcome message in the form of an unsolicited positive command response. The client must wait for this welcome message, and ensure it is properly formed, before sending any commands. Upon validating the welcome message, the client is free to send any number of commands, one at a time (each with any required parameters). The server will handle these as they are received. Communication between client and server must remain in lock-step at all times. Note that the server maintains a dedicated BasicEnrollmentManager instance for each client, until the client requests to terminate the network connection using the appropriate control command.
