RE: [opendiag] Digest Number 77

In addition to the Jeff Noxon's schematic & PCB layout on OpenDiag
http://www.opendiag.org there was an article in October's Circuit Cellar
magazine that had a serial port to ISO 9141-2 interface. The auther also
sells the interface and software.

There is also an effort to create free scan tool software in C++ on Linux.

Jeff, Uwe (& Dana?),

Now I must admit, this email thread left me a bit confused. What
I'd like to know is:

1. Is there any software I can use? (Open source, demo, inexpensively
bought, etc. This is a non-commercial application.) As a s/w
engineer, I could write my own. However, this is a time consuming
task.

2. Is there a adapter available? (I can easily solder up something
from a schematic.)

3. What will not work? So far I can only assume that Ross-Tech will
only work with VWs & some other cars, but not with my Toyota.

More Specifics - I have a 1994 V6 Camry with OBD-II. I not determined
if it is ISO 1941-2 or SAE 1979 or ... I do know that on a V6 (unlike
the V4), you cannot jump the TE1 & E1 pins to invoke the blinking of
codes on MIL light.
