As a spin off of my port of the Innovate Motorsports SDK I wound up with a collection of tools I wrote for the OpenPort 1.3 cable. This has now taken the form of an ActiveX control that handles basic connections and queries for ISO 9141-2, KWP2000, MUT, and SSM.
There is a simple test application which exercises the functionality and keeps a writable Debug Trace log (since I have so far really only tested on my wife's Lexus and two short sessions with an Evo).
The tool and control can be downloaded for Windows at:
http://www.innovatemotorsports.com/supp ... tSetup.exe
It installs to <program files>\LogWorks2 and creates the shortcut at LogWorks2\Tools, but LogWorks2 does not need to be installed.
The source for both control and test application are available here at:
http://svn.RomRaider.org/cabletools
Please keep me posted about compatibility and problems, I'd like to continue fleshing out protocols. Otherwise, enjoy.

P.S. Now that I have seemingly mastered SVN import (hooka!), I'll take a stab at my Java SDK next.
