ABSTRACT:
A system and method for supporting two infrared signaling protocols in a single computing device is provided. The computing system operates in a default mode unless a priority signaling request is generated by an application program. Priority signaling requests are given processing priority, and default mode transmission packets may be dropped during priority mode processing. Handling of dropped default mode packets is relinquished to an upper protocol layer of a network stack, which recovers and sends the dropped transmissions to the infrared device when the computing device returns to the default mode.
