This packet endpoint is in this state when we have acknowledged the
peer’s configuration request and he has not acknowledged us.

O

PENED

This packet endpoint is in this state when LCP negotiation has finished;
authentication, if enabled, is occurring now.

C

LOSING

This packet endpoint is in this state when we have sent the peer a "termi-
nate" request and are waiting for the peer’s acknowledgement.

C

LOSED

This packet endpoint is in this state when we have received the peer’s
acknowledgement to our terminate request; this will go to the initial state.
