Now that I got my cheap knock off Elm working, itwon't take the commands I'm trying to send it via Realterm. I can view data using the Scantool.net program but when I try to send commands via the terminal it just responds with a question mark every time. I downloaded the documentation from Elmelctronics.com and believe I am using the proper format using AT commands to address the device. Maybe whatever chip is inside the tool doesn't support the Elm commands. Any ideas? Thanks again.
Got this one figured out too...I had realterm set up to talk on the wrong Rx and Tx pins haha. I can now talk to the car using Realterm :)
