Author: n_hibma Date: Fri Oct 12 22:48:33 2012 New Revision: 241496 URL: http://svn.freebsd.org/changeset/base/241496 Log: 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.
