Can't really confirm the cable on another PC but it is a brand new cable from Belkin right out of the box. REALLY doubt that the cable is bad. I did verify that the com port is correct in my Bios (I am using COM Port 3 actually)and it is correct in Windows. For your final suggestion, regarding 4 colors in Workbench, this is a bit dicey because I don't have any way to use a monitor. So I am running the Amiga through a Hauppauge PVR unit and viewing onscreen using a TV application. (Hokey I know, but it DOES work, albeit with about a 2 second lag that is quite interesting) Anyway, the video is monochrome so I am not certain how to verify how many colors I am running. (Remember I am an old Amiga guy but it has been FOREVER since I have used one!) Thanks for your help...
