It may very well have the double head. It's not dropping any characters at 1200. I am surprised. That's 4x the expected speed! Here is another sighting of a Silent 703 working at 1200 bauds: https://ronsapartment.blogspot.com/2018/06/altair-duino-and-ti-silent-700.ht ml Says the author in the comments: "My Silent 700 came with a manual. So I went by that. I was pleasantly surprised that my Silent 700 had the "high speed option"." So there was a high-speed option for the Silent 703 apparently? Marc
