********************************************************************************
+Version 1.6 (04/2016)
+
+Fixed since Version 1.5:
+ BDM
+ Improvements to CPU register content display
+ T8 erase timeout period to 200 seconds (was incorrectly only 20 seconds)
+
+Added since Version 1.5:
+ T7 CAN functions:
+ Separate FLASHing algorithms for I and P-BUS connections
+ Completely safe, but slow, I-BUS algorithm
+ Pseudo 'recovery' FLASHing function can be used to retry a failed
+ FLASH with safe, slow algorithm
+
+Changes since Version 1.5:
+ Additional debug messages
+ T7 CAN functions:
+ Code refactoring to make file handling simpler
+
