OID_IRDA_LINK_SPEED (Windows Embedded CE 6.0)

1/6/2010

This object identifier specifies the link speed of the NIC's transceiver. Link speed indicates the speed that outgoing frames are transmitted and possibly the speed that incoming frames are received. For information on how to set OID_IRDA_LINK_SPEED to control the speed of incoming frames, see the description of OID_IRDA_RATE_SNIFF. Link speed is set to one of the speeds returned by the miniport driver in response to a previous query of OID_IRDA_SUPPORTED_SPEEDS. The link speed is specified in bits per second (bps).

The specified link speed applies to all frames subsequently transmitted by the miniport driver. The miniport driver may still have frames to transmit at the old link speed (the link speed in effect before the set of OID_IRDA_LINK_SPEED). The miniport driver should transmit these frames at the old link speed. The link speed specified by OID_IRDA_LINK_SPEED applies only to frames sent after the miniport driver is notified of the new link speed.

After the miniport driver starts, it must assume a link speed of 9,600 bps, regardless of the value in OID_IRDA_LINK_SPEED.
