It is quite likely that I came across it, but then forgot about it (after all, I had to read the 33F UART doc to write code for the custom library 1.5 years ago). Happens to me often nowadays, perhaps because I've been spending majority of my time on non-PIC related stuff. ;-( I think it's pretty cool that the PICs are so flexible. They give the engineer a lot of options, and the scary complexity can be neatly tucked away behind a simple interface. Looking forward to the time when I can put everything else aside, and get back to coding! :-) Vitaliy -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
