Jose Souto, I really enjoyed reading your "IR to SERIAL Interface" posting. What I liked was the excellent, clear description of the algorithm you used. It is often very time consuming to read through someones code and try to figure out the algorithm; your concise explanation made it clear to me. In general, my tastes very much prefer postings of algoritms rather than code. Any idiot can write code (me for example). The real problem is what to write - ie., the algorithm. Thanks! Tom Messenger
