Zusammenfassung:1. Field of the Invention A system to adapt the MAC rules of the IrLAP specification to accomodate various IR transceiver devices with media sense utilizes an IrDA protocol stack having a series of layers including:where LSAP is the Link Service Access Point. This kind of protocol stack can be applied to a very large variety of devices, such as, remote controllers with feedback for tuners; can be used for data transactions by request, e.g., pager reporting of received numbers; and is applicable to data acquisition systems, such as, portable GPS reporting of changes of location and medical systems. Various ways for implementing the invention comprise: using the connection-less data service; using XID frames; or using proprietary or open object definitions; with the use of the connection-less data service that is already present in the IrDA specification along with the emerging OBEX object definitions being preferred. Implementation requires no changes in existing systems, and the open service specification ensures connectivity between systems from different vendors.
