Hello, I have a problem whereby if the low-level comms supporting a network interface I'm using for LwIP suddenly (and unexpectedly) disappears, the upper stack layers don't seem to be becoming aware of this. I'm using the PPP network interface, but I don't think that should make any difference to the question in principle.
I am able to determine when the data channel goes down (via a callback), so can anyone say if there is a variable or data member in the upper layers that I should be modifiying on this event, to indicate that there is no longer a means of tx'ing/rx'ing packets? Perhaps the variable is actually in the network layer (PPP in this instance)? Kind regards, Clive Wilson _______________________________________________ lwip-users mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/lwip-users
