I have PICDEM2-PLUS demo board with 18F452 , W2K , MPLAB 6.40, and running demo p18demo -project from Microchip Debugging and programming going well, but when I connect the board to my PC via RS232 cable I can not see the proper character on HyperTerminal. Coming strange characters as: Xfxx~~xffxxfxxxZpZpZpZpZpZpZpZpZpZpZp What is wrong with the RS232 communication? Is it normal to se such characters on Hyper Terminal. I tried to set all possible settings does somebody has such an experience here? I wrote a simple application in vb.net MsComm but the results are the same. best regards Krasimir -- http://www.piclist.com hint: The PICList is archived three different ways.
