I really had a hard time calling pppos_input() or pppos_input_tcpip() passing data byte after byte. Every time I got bad FCS. So I had to handle the UART input and delivery the whole PPP frame with 0xFE .. 0xFE to pppos_input. After that something started to work. But that is really weird because the AT commands work very well, even with ECHO on.
