Hello Patrick, Thanks for the feed back. Per your input, there are few issues that I did like to clarify. 1. I have a single UART and I don't believe that I could be tapping the wrong line. During PPP negotiations, I do see the data on the logic analyzer. Once IP address has been received, I no longer see incoming data on the logic analyzer/
2. I am also convince that the incoming data never gets on the UART after connection for the LWIP stack to handle it. 3. When I halt the microcontroller and send ping to the IP address, the device is still responding to the pings which levels me to believe that the modem is responding instead of the LWIP stack since the micro is not running. 4. By transparent passing, I meant, the data should not be process internally by the modem but instead sent over the UART channel and allow the LWIP stack to handle all processing. -- Sent from: http://lwip.100.n7.nabble.com/lwip-users-f3.html _______________________________________________ lwip-users mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/lwip-users
