This read-write object is the administrative control for the Bridge Network Control Protocol's finite state machine on a PPP link, taking open(1) or close(2). An admin sets it to inject an administrative open or close event, forcing the bridging NCP to attempt negotiation or tear itself down independent of the underlying PPP link state. For example, setting this to close(2) on a misbehaving bridged link forces the BNCP session down so it can be manually reopened with open(1) to retrigger negotiation.
