Well i do nothing manual , all i did after installing the modem drivers
was to setup a connection using KPPP , so i don't really know what
KPPP did .

The real strange thing to me is that it says "could

I don't know that much to tell you what is causing this , perhaps
it is just the most suitable error message that pppd could find to explain
the error situation it encountered .

The above lines just say when the modem should abort the
attempt to connect .

The exact response to each AT command depends on the modem
usually the AT(Tention ) responds with a status report of the modem .
If you have KPP available give the "Query Modem"  command ,
the output you will get is the result of the "AT "  command .

Well you should leave it without the w.x.y.z:a.b.c.d thing so that 
things will
be configured automatically . My ISP sends me all the required settings
automatically .

My best bet would be to agree with your assumption . Well pap-secrets
and chap-secrets are equivalent . Their use depends on your ISP , if
your ISP is using the Password Authentication Protocol ( PAP ) to 
authenticate
you then ppp-secrets is used otherwise if the Challenge Host 
Authentication Protocol
( CHAP ) is used the chap-secrets file is needed .

  Or are there other files

No i would vote against a ppp bug because i lack the knowledge and the
evidence to prove it .
