Re: [lwip-users] [Issue] TCP fragmentation over PPP - fragments are lost in LwIP if data is queued for sending

Well, on a system with PPP *and* standard ETH, you obviously can't wait for the serial interface to transmit before serving ETH?

Again, it can't happen, lwIP is mostly sequential, the lwIP stack is (or 
should be!) waiting while you are sending data over the uart port.
