After making this change, I could connect
/etc/ppp/peers/kppp-options => file content is set as noauth

but within few minutes I get this error


The pppd daemon died unexpectedly!
Exit status: 16
See 'man pppd' for an explanation of the error codes or take a look at the kppp FAQ on http://developer.kde.org/~kppp/index.html

Again sometimes I get NO CARRIER message!
