Re: [lwip-users] PPP server problem

[LMao]

Hi Sylvain,

Thanks for your help. Yes, you're right. I was using the wrong PPPoS input 
path. I should have used pppos_input_tcpip() instead of pppos_input() in my 
circumstance. 

Regards,

Charles

You didn't answer fully, which PPPoS input path are you using ?  There are 3 of 
them and only one of them is right for NO_SYS = 0.

Why is the last message truncated ? Are you buffering debug print ? If 
yes, could you remove the buffering so we may have the latest output ?
