Hi. recently bought cnc machine that came with desktop with alphacam installed. I want to install alphacam on a laptop so I can do drawings at home and ready them for next day. trouble is the dongle for the software is a 25pin serial port that will only run on xp. Any suggestions how I can work at home without using a huge desktop pc. I know you are thinking usb to serial cable but the previous owner says they won't work. Fingers crossed someone will come up with a solution. Steve
