/* ThroughHardwareSerialRs485AutoTx enables PJON multi-master communication through the Serial port with auto-tx RS485 PHY.
   Work based on ThroughHardwareSerial by Giovanni Blu Mitolo and Fred Larsen  
   Copyright (c) 2016 by Zbigniew Zasieczny All rights reserved.

   With rs485 "auto-tx" PHY the hardware serial port reads everything sent to the bus
   The "self-reading" property could be used in this strategy to detect colisions at a byte-level in a similar way the CAN network works on a bit-level to silelntly drop-off lower priority nodes; feature not implemented yet

   A naive timeout-based collision avoidance is used: bus is assumed clear for tx within specified time window after empty rx buffer was detected. The receive(<timeout_us>) function must be called often - transimission would occur only within 1ms after last receive call on empty rx buffer; within this time window the update() function must be called to transmit packets.
