Hi all.

During ppp connection, very often it happens that it sticks, i.e. it's still
open but it's not possibile navigate, browser can't open pages.  Then I do
`C-c' from command line and the connection stops showing the above message.
Please help, whoever can, about diagnostic and - possibily - solution of the
problem.

Thanks,

Rodolfo
