Do you have the actual ALDL160 protocol standard?
You can read it at 160 baud all day, but without the protocol or knowing how the data is formatted, the numbers are going to be jibberish on the LCD and useless.

And, for me anyways, a Google search on '160 baud aldl' brings me a whole load of decent links with hardware, software, and at the very least, a base to work with....if I was building an ALDL reader....which I'm not....
