Description: When setting this object to the value of close (2) the indicated port on Tau is instructed to be closed after the next reset. Setting to the value of open (1) does not guarantee the opening of the indicated Tau port after the next reset but will only allow the Tmu system to let this port into the ring if it obeys the rules of token ring. Reading this object returns the value last set by the manager (or the default value). This command only affects ports on Tau. If there is no Tau attached at startup (after reset), then it is stored in memory and goes into effect when a Tau is attached. This command will have no effect of a station directly attached to the Tmu. To permanently detach a directly attached station, use 'fibTmuPortsManagerClosePerm' (See above).
