Using the Dallas 80C320 with Keil evaluation software. I am seeing the data sent to the Uc echoed back to the sender. I am not intentionally echoing the data. I can't find any mention of this in the data sheets or the Keil website. Anyone have any ideas?
Oops, I shoulda remembered this. In this case, the echo is done by the Keil getchar routine. Note that this is documented in the C51 User's Guide. The following knowledgebase article discusses this as well as a workaround. http://www.keil.com/support/docs/1791.htm Jon
