Basic wireless link between hosts
The data flow sequence is initiated when the first byte of data is received in the DI Buffer of the
transmitting module (XStream Module A). As long as XStream Module A is not already receiving
RF data, data in the DI Buffer is packetized, then transmitted over-the-air to XStream Module B-0
