Re: Mobile Broadband - disconnect after 2 mins.

Thanks for the reply, Dan.  I didn't see these replies until after I
submitted comments on the bug report.

In those comments I gave you the appropriate syslog entries showing
that pppd logged four unsuccessful LCP echo requests and terminates
the connection after 2.5 minutes.  Boooo!

Your work towards overriding pppd's default options looks like it
should do the trick.
