By the way, this is a great example for PPPoS I forgot I did, this should definitely reach the doc folder :-) > Can you give an example application code snippet for threaded > environment?

Note that lwIP should be initialized before and it must finish its initialisation before calling any of ppp_ or pppapi_ functions. Sylvain
