I think it's the computer - the COM port isn't active - tried connecting a serial mouse and a digital camera with no success for either.
Anyone have any suggestions on how to diagnose it? I've been messing around and not getting anywhere. Win 98 on an old p120 laptop. Device manager says the serial port is enabled and working properly...
I just don't know enough about the hardware to say it's "good" or not, or whether it's only a hardware/software compatibility issue.
Reading around online, I have learned that not all the programs work with all the hardware, despite supposedly being built on open standards.
Essentially I bought hardware built by hobbyists, and am attempting to run it on software written by hobbyists. In retrospect, the smart move would have been to get both pieces of the puzzle from the same hobbyist (like the guy in TN, whose program screen shots I posted above).
Depending on what language the source is written in, you might be able to make your own mods to it. I think that's what I'm looking for, though it's always nicer to find it already written and stable. And of course if it works and you have the source, it (or part of it) might be ported to other platforms like Palms and cel phones. Maybe.

Spent another hour plus on it today: Re-installed EVERYTHING on my old laptop (so I can give the borrowed one back) and got the COM port to talk to the scan tool. And I think I found a program that will do logging, and it also appears to be able to talk with the tool.
I'll have to look into it a bit more this weekend. Quel grand ordeal.
