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

Host A sends serial data to XBee Module A
After T , contents of D Buffer
are assembled into packet and transmitted
TX/PWR LED on XBee Module A pulses off
briefly to indicate RF transmission
If 16-bit CRC checks out, data is shifted out
