    The pc's serial port control lines are resetting the Stamp.

    When used for communication (not programming) just make up a cable with no connection to pin 4 (on the Stamp end).

    I think the newer Stamp boards have two capacitors on pin 4 which will still allow a reset but it won't hang the Stamp. Have a look at the diagram for the Stamp Carrier Board or any of the others to see how to connect the capacitors.

    Cheers,
