svx_commuter, Vikash indeed had a tool for interfacing with the first-gen Legacy. I still have a copy of it, as well as a laptop (which is currently dead, oh well) to run the DOS-based software on. But it's not very useful for the SVX.
Phil (b3lha) has been working on an SVX version of the tool, which appears to work right in Windows too. And considering Phil's talks to the TCU, cruise computer and climate control... yeah.
Thanks for the link, but progress is already being made in this direction.
