I was using the eCos PPP stack in conjunction with an EB40A, and I was able to establish a link w/ a Linux peer flawlessly (btw, thanks for the cool stack--I was able to create a program in Linux and have it immediately work in eCos!); however, when trying to connect to another device (in particular, a Kyocera 1xRTT module), a link never occurred (i.e., the Kyocera module never even tried to respond to PPP packets sent). Further inspection showed that the eCos stack did not send out an initial "flag sequence", and I assume the module timed out before the next frame was sent (i.e., wasn't able the use the previous ending "flag sequence" as the beginning "flag sequence" of the new frame). I modified the code in "pppasyncstart" such that the "flag sequence (0x7e)" is sent before every frame, and this seemed to worked great for my application; however, I'm not sure this would be best for all users since a "NULL frame" would possibly have to be digested by all possible peers. Anyhow, let me know if this is the right way to go. Thanks for the great operating system. John Paul King
