OID_WW_GEN_SUSPEND_DRIVER
As a query, the OID_WW_GEN_SUSPEND_DRIVER OID requests the miniport driver to return its current suspension state.
As a set, this OID requests the miniport driver to change its current suspension state.
In either case, this request uses one of the following values:
| Value | Meaning |
|---|---|
0 |
Driver operational |
1 |
Driver suspended |
When a miniport driver suspends itself, it should release any hardware resources, such as the serial port, it uses in its operational state. This operation can be initiated in Control Panel when an end user wants to reassign the hardware resource for other uses, such as sending AT commands to a serial device on the same serial port that the NDIS driver was using.
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 driver's suspension 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.
