The only challenge would be detecting the rate and byteorder.\n","author":{"url":"https://github.com/matthewmgamble","@type":"Person","name":"matthewmgamble"},"datePublished":"2014-08-07T02:03:30.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/4/codekit-java/issues/4"}
