IrDA Miniport Drivers

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 x has been deprecated and is superseded by NDIS 6.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.

The Infrared Data Association (IrDA) has defined a half-duplex protocol for encoding data frames as infrared light pulses. Infrared transceivers are created to transmit and receive these infrared light pulses. These infrared transceivers consist of a transmitter light emitting diode (LED) and a receiver diode. The receiver diode is sensitive to transmissions of infrared light pulses that it receives from a remote infrared LED that is located a short distance away. The transmitter LED must transmit infrared light pulses to a remote receiver diode that is located at the same distance.

An infrared adapter is a type of network interface card (NIC) that combines an infrared transceiver with supporting hardware for encoding and decoding frames. An IrDA miniport driver is implemented to control an infrared NIC.
