Although I did the port for PPP to NO_SYS=1, I'm not sure I can help you that 
much since I'm not really a PPP expert, I only used the code while testing 
during development with a simulated COM port.

Calling pppos_input() that way should be OK. Blocking functions must not be 
used for NO_SYS==1.

I think the PPP setup should be fine. As I'm really not a PPP expert, I can't 
tell why you get a bad fcs. I remember getting this also sometimes, but Iordan 
(who helped me with PPP bugfixes) said it might be due to me using a virtual 
COM port... Maybe he can comment on this if he still reads this list...
