Johan, this is a very simple problem. You can read and send the values from the A/D ports as follows: int x; hwcom.init(); ' initialize COM to 9600 Baud, No Parity and 1 Stoppbit x = ports.adc(1); ' read the value hwcom.put(1); ' send the analog port number hwcom.put(x / 256); ' send the high byte of the value hwcom.put(x mod 256); ' send the low byte of the value hwcom.put(13); ' send carriage return (e.g.) as end of record indicator for synchronization between records. Depending on your reading equipment you must perhaps also define a startbyte, as the carriage return may also be identical to a mesured value. This would rise problems in recognition of end of record. I hope, this will help you a little bit to perform your task.
