it seems like the HB is not able to talk back to your PC. make sure the TxD signal starting from the 'hc11 is leaving the HB properly at the RJ11, reaching the interface bd, and then being cvt'ed to -10v to +10v levels out the interface bd on its (...)

(...) Why does it make the ports useless for other sensors? If you need a pullup-resistor, you can still solder a 47k resistor directly to your sensor-connector between Vcc and Sensor in. Thus in my opinion the HB can be used more flexible without (...) (25 years ago, 9-Mar-00, to lugnet.robotics.handyboard)

I recently finished collecting all the parts for the handyboard and started assembly. I went all the way through the i/c board setup without a hitch. But when I got to assembling the serial comm circuit a few things went wrong. I assembled the (...) (25 years ago, 9-Mar-00, to lugnet.robotics.handyboard)
