OID_WW_TAC_TRANSMITTER_KEYED
The OID_WW_TAC_TRANSMITTER_KEYED OID requests the miniport driver to return a Boolean indicating whether the NIC's transmitter is operating. A value of TRUE indicates the NIC's transmitter is currently operating. A value of FALSE indicates it is in a quiescent state.
Typically, this OID can be used to provide users information about the state of the NIC's transmitter. That is, provide users a transmit indicator.
If any bound protocol has enabled indications with OID_WW_GEN_INDICATION_REQUEST, the miniport driver must call NdisMIndicateStatusto notify such protocol(s) if the operational state of the NIC's transmitter changes. It can ignore the TriggerValue member that was specified in the OID_WW_GEN_INDICATION_REQUEST.
Sets are irrelevant for this object.
