    Most likely your kit requires a 25-pin parallel printer port ("LPT port"), not a COM port.

    So if your PC does not have a parallel printer port, you may have to find a PCI parallel port add-on card to plug into your PC and then you can plug the 25-pin cable into that.

    Is your computer a desktop or laptop?

    If it is a desktop you can add a PCI parallel port card and use the 25 pin parallel cable. If it a laptop you can use a USB controller board like a KFlop, or a SmoothStepper.

    You can use a SmoothStepper or KFlop with a desktop as well.

    A USB controller is a better choice than a parallel port, as it will provide a better stream of steps for your machine.
