gertk 0:28557a4d2215 7 --------
gertk 0:28557a4d2215 8 2007-03-08 status of LED output was set to 1 (LED-ON) during config, must be 0 (LED-OFF)
gertk 0:28557a4d2215 9 2006-06-22 changed baudrate to 115K2, this is more practical/compatible with the bootloader (currently)
gertk 0:28557a4d2215 10 2006-06-21 added complete device configuration word, witout it the source is not complete
gertk 0:28557a4d2215 11 in previous versions the user had to set the configuration word within MPLAB
gertk 0:28557a4d2215 12 but to make this source independent, the configuration word must be included here!!
gertk 0:28557a4d2215 13 and NOT in the development environment. Doing it within the source also documents it.
gertk 0:28557a4d2215 14 2006-04-12 enabled interrupt on RB0 (for ATN handling under interrupt)
gertk 0:28557a4d2215 15 2006-03-28 change in IO-pin definiions required for new PCB design
gertk 0:28557a4d2215 16 2006-02-04 added timer-0 (for the led blinking routines)
gertk 0:28557a4d2215 17 2006-02-02 improvements in code layout... i.o.w. making it more readable
