I have also had problems and mishaps with the various downloaders... Sometimes DL will work in a full-screen DOS box, other times it doesn't. HBDL seems to work now, whereas it hadn't previously. I have no clue what is causing these to work or not (...) (26 years ago, 24-Jun-98, to lugnet.robotics.handyboard)

Is the ir emitter on the handyboard just a standard red led? Is it efficient at emitting in the IR range. Are there better emitters? I want to build an emitter and detector set and have studied the multiplexing circuit posted. It uses the same LED. (...) (26 years ago, 24-Jun-98, to lugnet.robotics.handyboard)

it sounds like it's *almost* working. 1. did you try DL, not DLM, in full screen dos mode? 2. try both of these as a DOS program. 3. did you try adjusting your serial port parameters in the windows control panel, a la the FAQ? fred (26 years ago, 23-Jun-98, to lugnet.robotics.handyboard)
