Overview
1-12 Communications Services
The communication architecture is flexible, supporting complex communication
needs. The architecture is also extensible, allowing new communication transport
tools to be added dynamically and accessed through the same interface as existing
transports. In this way, new communication hardware devices can be supported.
The Newton communications architecture is illustrated in Figure 1-2.
