         set timeout 0
         set log phase chat connect lcp ipcp command
         set authname *******
         set authkey *****
         set dial
         set login
         add default HISADDR
         disable pap
         disable ipv6cp
         enable proxy
         accept dns
         enable MSChapV2
         enable mppe
         set mppe 128


but it does not work
