Author: n_hibma Date: Thu Oct 25 21:08:31 2012 New Revision: 242098 URL: http://svn.freebsd.org/changeset/base/242098 Log: MFC 241496: Some 3G modems return the wrong signature in echo packets and make it impossible to use LQR/ECHO. They return want_magic instead. With this change it is now possible to use enable lqr set lqrperiod 5 enable echo set echoperiod 5 in your ppp.conf file.
