+    --------    
+    2007-03-08    status of LED output was set to 1 (LED-ON) during config, must be 0 (LED-OFF)
+    2006-06-22    changed baudrate to 115K2, this is more practical/compatible with the bootloader (currently)
+    2006-06-21    added complete device configuration word, witout it the source is not complete
+                in previous versions the user had to set the configuration word within MPLAB
+                but to make this source independent, the configuration word must be included here!!
+                and NOT in the development environment. Doing it within the source also documents it.
+    2006-04-12    enabled interrupt on RB0 (for ATN handling under interrupt)
+    2006-03-28    change in IO-pin definiions required for new PCB design
+    2006-02-04    added timer-0 (for the led blinking routines)
+    2006-02-02    improvements in code layout... i.o.w. making it more readable
