Hello, i am using lwip 1.3.2 + PPP with FreeRTOS.
I have a question about pppInProc.
When i receive a ppp packet which start by 0x7E, when the function is testing the fcs: he found an invalid fcs and drop the packet.
I don't understand why ( i have already read rfc but i'm lost).

perhaps, the packet is wrong: my sio_read return only the packet between 2 flags 0x7E. An didn't return "CONNECT 115200" from the modem GPRS.
