Maybe I'm abusing the thread .. my ELM327 arrived today. I'm happy.

pyobd on N900 can connect to it, but not ECU. Basically after ATE0 command sent to the ELM327, no more activity through pyobd.

Got a friend's Android, and Torque immediately started communicating and receiving sensor data.

i tried minicom on N900 but that was even worse. when i manually type ATZ, there's no response after hitting the "enter" key, and the prompt does not return. i think the connection is correct, as the ELM327 does light its LEDs while i type each of the letters "A" "T" and "Z." Maybe N900/minicom is not sending the correct "Return" key?

Will try again with minicom over the weekend and report back.
