I am new to this forum and fairly new to CNC (and many may say new to computers, based on my question). I have been told different things, by no one with conviction, about the best(and cheapest) way to download files from a new laptop with no serial printing port and running XP to my school's CNC which receives on a serial cable. I have heard of USB-Serial converters, but that each has specific applications. Can changes be made in BIOS to change the parallel port to run as serial? Would the Mastercam Hasp then still work? I would appreciate any help. Thanks
