[lwip-users] lwIP : Interface Ethernet <-> rs232

[Bruno BOURDAS]

            Hi. I’m a newbie (sorry…). It is my first development with the networks protocols.

 

            I must make an interface Ethernet (UDP/IP) <-> rs232 (UDP/IP/PPP) to transfer data.

 

            I wish to use the API functions of lwIP.

 

For Ethernet link, it’s ok. I am using the functions FD _..., select, read, etc.

            But I do not see how to establish the link with layer PPP

 

            How to bind the API functions to the layer PPP ?

 

            Do there exist examples of code about that ?

 

            I thank you in advance for all ideas which could help me to advance in my problem (small I suppose).

 

            Best regards
