 If you used the \`persist' option in your pppd settings, you will notice
 that pppd will not redial infinitely anymore, instead it will redial
 ten times, and quit.

 A new \`maxfail' option was introduced to change this. To get the old
 behaviour, you will have to add \`maxfail 0' to your pppd settings.

 Details about this can be found in /usr/share/doc/ppp/README.Debian.gz
 file and in pppd(8) manual page.
