Two more questions: How does the sample server in AN833 change without the picdem board and also, CLOCK_FREQ = 20,000,000 do I need to change this to fit my internal oscillator or does it sort itself out? Lastly, where do I define the Defines, for example, to choose tcp I need to define STACK_USE_TCP, but where do I define this? thanks tim. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
