I don't see the logic ever reaching the check_passwd() when I set ECOS
device as PPP server. I think fundamentally the ECOS PPP Server
authentication has been broken. 

In the lcp_init() function, there are following lines:
    wo->neg_chap = 0;			/* Set to 1 on server */
    wo->neg_upap = 0;			/* Set to 1 on server */
But I am not sure what these lines are for. I changed to 1 for both
neg_upap and neg_chap, still the same result. Another place is in file:
pppd.c

    int  auth_required = 0;	/* Peer is required to authenticate */

What is this line for?

Thanks a lot!
