Jim and Gene,

Thanks!

The RS232 pins are an EXCELLENT IDEA! As a computer geek, I'm surprised I did not think of that earlier. Thanks again.

Jim,

Based on your website, below are 10 different "systems " that I check codes for. Each one uses a different pin on the X11/4. Is this true? Are these all available to my 94 E420 (California)? Any others that I'm missing?
