Open Source To The Rescue!īefore trying anything yourself, see if someone else has done the hard work for you. So it is up to fearless hackers to reverse engineer what they've done. Reminds me, I need to do a GPL request to Vestel. ![]() Neither Vestel nor Cabot are interested in providing documentation, or any technology support.
