3.2.4 I/O Change of State/Cyclic Messages:
The Change of State Message is transmitted by either the Master or the
Slave. A Change of Sate/Cyclic is directed towards a single specific node
(point-to-point). An Acknowledge Message may be returned in response to this
message. Within either the Master or the Slave the producing Change of State
Message and consuming Acknowledge Messages are received/transmitted by
one Connection Object. The consuming Change of State and producing
Acknowledge Message are received/transmitted by a second Connection
Object. The architecture for these messages can be seen in figure 3-6 and
