It probably won't work for you then. I originally bought mine from eedesignkits because it was the only USB solution at the time. Those clowns have taken the SEN/STA pin on the Melexis chip and grounded it. This forces the Tx line open and shuts off any bit comparison between the Tx line and the iBus - ie. no hardware collision detection and no method to monitor the bus activity. I've since switched to Rolf Resler's V5 USB version. It will allow you to monitor the DSR, CTS, or CD lines. I used a handy little program called COM Port Toolkit 3.6 to test both interfaces. Try it on the eekit and you'll see what I'm talking about - the status lines will all stay high no matter what kind of ibus activity is going on. They should take the 'hardware collision detection' bullet off their site, it's simply not true.
