Kind of off topic but may be relevant for future users. Stevo's awesome stuff only works on win7 or newer. I tried and tried to have it work via the serial port I have on my lappys. It never worked. If I used a keyspan(ftdi) usb to serial, it worked perfect. After much traffic logging it appears to be a windows problem although I was able to use John's(Tunercat) with Win7 and the serial port but the logging showed an incredible amount of retries that I don't normally see. It's like the newer windows stuff doesn't understand the original serial stuff, bleh.
