Changes in Teensy libraries
===========================

Activate 9 Bit UART support
---------------------------
  ...\Arduino\hardware\teensy\avr\cores\teensy3\HardwareSerial.h

// uncomment to enable 9 bit formats

#define SERIAL_9BIT_SUPPORT


Increase TX buffer to avoid "busy waiting" while sending JETI data blocks
--------------------------------------------------------------------------
  ...\Arduino\hardware\teensy\avr\cores\teensy3\serial2.c
#define SERIAL2_TX_BUFFER_SIZE     128 // number of outgoing bytes to buffer


Changes in Teensy HardwareSerial library in order to receive Jeti keys
You dont need it, as long as you do not interconnect RX2 and TX2
