All, I am going to be developing a proprietry serial interface to a piece of hardware using an RS232/UART mechanism. Is anybody aware of a simple 'RS232 Monitor' box that I can fit inline to help debug/decode the binary data being exchanged? thanks, SW. -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
