Yes, same here, all modules I know are TCP/IP capable and PPP capable. The OP mentioned some modules/chipsets which are not TCP/IP capable and I assumed they weren't PPP capable also. As long as the chipset/module supports PPP, you rule and dinner's ready. Otherwise, long way to walk on the netif road. -- _______________________________________________ lwip-users mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/lwip-users
