OID_WW_GEN_DISABLE_TRANSMITTER
As a query, the OID_WW_GEN_DISABLE_TRANSMITTER OID requests the miniport driver to return the NIC's current transmitter status.
As a set, this OID requests the miniport driver to put its NIC's transmitter into the requested state.
In either case, this request uses one of the following values:
| Value | Meaning |
|---|---|
0 |
Transmitter enabled |
1 |
Transmitter disabled |
-1 |
Transmitter state unknown |
A typical use of this OID is to immediately disable the NIC's transmitter without regard to system or user traffic. The affect of this OID depends on the particular NIC. Some NICs might only disable the physical transmitter, while others might fully shutdown thereby disabling reception as well. The miniport driver should return NDIS_STATUS_INVALID_DATA if the value at InformationBuffer of NDIS_REQUEST for this request is invalid or -1.
If any bound protocol has enabled indications with OID_WW_GEN_INDICATION_REQUEST, the miniport driver must call NdisMIndicateStatus to notify such protocol(s) if the NIC's transmitter state changes. It can ignore the TriggerValue member that was specified in the OID_WW_GEN_INDICATION_REQUEST.
Note This OID is not available for use beginning with Windows Vista.
