### Unifying communication methods ### Unifying communication methods
In networked A/V systems, devices can use many different methods of communication. Com ports; TCP/IP sockets; Telnet; SSh... Generally, the data protocol and commands that are sent and received using any of these methods are the same, and it is not necessary for a device to need to know the details of the method of communication it is using. A Samsung MDC protocol display in room 1, using RS232 speaks the same language as another Samsung MDC does in the next room using TCP/IP. For these, and most cases where the device doesn't really need to know its communication method, we introduce the `IBasicCommunication` interface.

All common communication controllers will implement the `IBasicCommunication` interface, which is an extension of `ICommunicationReceiver`. This defines receive events, connection state properties, and send methods. Devices that need to use Com port, TCP, SSh or other similar communication will require an `IBasicCommunication` type object to be injected into them at construction time.

Essentials uses dependency injection concepts in its start up phase. Simply, most devices use the same methods of communication, and are often communication-agnostic. During the build-from-configuration phase, the communication method device is instantiated, and then injected into the device that will use it. Since the communication device is of `IBasicCommunication`, the device controller receiving it knows that it can do things like listen for events, send text, be notified when sockets change.

Classes that are using socket-based comms will need to check for whether the communication is `ISocketStatus` and link up to the `ConnectionChange` event for connection handling.
