Yes COM1 is the only port I use, my laptop has no other serial ports (a part from COM4 when I use my MEGA i dont know why its like that)
Nothing had shorted out, as nothing had changed, it was talking back to my pc when it felt like it after I uploaded the colour sensor code, it was a weird one, I am currently using Win 7, and it shows the "usb to rs232" when plugged in.
Thanks
