I went to your site and downloaded Driveline, but it gave me an error when I tried to run it; "Component 'MSCOMM32.OCX' or one of it's dependencies not correctly registered: a file is missing or invalid". I am not running VISTA. I guess this seems to be a common problem with VISTA.
Also, I'm very excited that you released the source, I plan on using it as my base. Thank you VERY much.
