LCP is the ppp Link Control Protocol. LCP negotiates line settings
and other features. Since ppp can carry many protocols on top of it,
its probably complaining that it can't carry a specific protocol
that was requested. Probably a communications error or something.
Sometimes it is said that man can not be trusted with the government of

found angels in the forms of kings to govern him? Let history answer this
question. -- Thomas Jefferson, 1st Inaugural
