Your success using a USB to serial converter will depend on the CPS you're using, the computer, the OS, the specific make and model of serial to USB converter, and it's drivers. All that, and a fair smattering of luck.These are serial ports, could you use a serial to USB to connect to the computer?
Be prepared to try various compatibility modes, if it doesn't work at first. I've had some CPS and some computers balk at Windows 7. Even different computers of the same make, model, and OS have taken different steps to get working right. But it CAN be made to work.I have the CPS and plan to use Windows 7.
