Description: When setting this object to the value of close (2) the indicated port on Tau will be closed, the related led will start blinking at a slow rate and port will not be opened before it is set to the value of open (1). Setting to the value of open (1) does not guarantee the opening of the indicated Tau port 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 holds only until the next system reset. To make sure it remains valid after reset, use 'fibTmuPortsGenClosePerm'. This command only affects ports on Tau. If there is no Tau attached when command is issued, 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 detach a directly attached station, use 'fibTmuPortsManagerCloseRun' (See above).
