/* Overview */
FixmeBus is a field bus based on the half duplex [http://en.wikipedia.org/wiki/RS-485 RS485] famous hardware protocol. It is a master / slave architecture, with every slave chained together.
===The communication protocol is a standard UART, ...===... which has these following parameters:
*38,400 bauds
*no flow control
Each end of the bus is terminated with a 1% 120R resistor. The A/B lines are biased at one end with 2x 1kOhms resistors.
===Every data frame on the bus is like this (byte on the left = first byte)contain chronologically:===
*2 bytes of slave adress (ID_HIGH and ID_LOW) => 65536 slave adress
