Because TI is weird TI graph link is no longer avaliable for download anywhere on TI website, except if you go on the connectivity kit page, and click on the serial ti cable info link. There you'Ll have your download. but so you dont have to search hours to find it here's the direct link: http://education.ti.com/educationportal/appsdelivery/download/download_interim.jsp?cid=us&displayMode=F&applicationid=161&contentpaneid=7

mostly for the people who want to edit programs on the PC. There is still source coder as alternative but I dunno if its finished yet so it may not be as reliable  

well maybe we should have a list of useful software then pin it
