Issuing Commands to Communicate with Devices (NDIS 5.1)
Note NDIS 5. x has been deprecated and is superseded by NDIS 6. x. For new NDIS driver development, see Network Drivers Starting with Windows Vista. For information about porting NDIS 5. x drivers to NDIS 6. x, see Porting NDIS 5.x Drivers to NDIS 6.0.
A miniport driver with a WDM lower edge that controls devices on a bus issues commands to the bus interface to communicate with those devices. For more information, see Handling IRPs. See also the documentation for the particular bus-driver interface.
