I have a lc-1 with V-1 and RR. I have a new laptop with window vista that has no serial in port. I have went to radio shack and bought a serial to usb cable. The laptop could not find the drives for the cable. The cable even came with the driver disk. I also tried the radio shack website with there updated driver info and still no luck. I took my laptop to the guys at radio shack with the cable and they could not get it to work either. They told me it must be a window vista problem because on the cable box it say window 98 to XP if I am correct but nothing about Vista. Is there anything else that I could try or use beside having to load XP on my Laptop. If anyone has bought a serial to usb cable and had luck install it on a window vista laptop please chime in.
