    It depends entirely on how the device specifies the RS232 protocol. You will have to check the data sheet. Once you know how the protocol works, you can try to send stuff to it through a terminal program.

    (If you think Hyperterminal stinks, at some point I posted the source on this site for a whole terminal program that could read/write binary as well as ASCII symbols. It is somewhere on the C/C++ boards...)

    Once you can send things through a terminal program, then learn how to send commands automatically through the Windows API. There is plenty of topics for how to do that on these boards. Here is the raw API manual:
