    And now we search your past post to find the code. Yeah-right.

    If you are going a shout distance the MAX is not needed. Make sure the signal is inverted if sending to a PC.

    The resistor is for current limiting.

    Not quite mackrackit,

    that was not my intention !

    I just simply wanted to say that the code was previously showned in diferent issues and that my question here on this thread did not required ( IMO ) all the code for the exception of the debug line it self.


    "If you are going a shout distance the MAX is not needed."

    By this you mean short distance ?

    I have gone 30 feet with no problems. The MAX chips are good if you need to invert the signal and you can not do it at the source and to raise the signal levels to +-12v as is standard for RS232. Making longer distances possible. Have reached around 80 feet this way. If the location is not noisy and the cable is good (CAT5 does not get it) the distance could be more.
