Appeal No. 2001-0161
Application No. 08/784,087
specification to accommodate various IR transceiver devices with
or without media sense. See page 3 of the specification.
Independent claims 13 and 22 are reproduced as follows:
13. A method of defining an IrDA protocol stack having a series
of layers, for providing transaction support for IrDA-compatible
systems including at least a transceiver device and a host
adapted for IR transmissions therebetween, comprising the steps
of:
providing a Connectivity layer defining the operating
conditions for a physical IR link between said transceiver
device and said host;
providing an Ir Link Access Protocol (IrLAP) layer,
cooperating with said Connectivity layer, defining the
specification for establishing a physical IR link between
said transceiver device and said host, and comprising:
Media Access Control (MAC) rules for the IrLAP
specification defining the requirements before the
initiation of an IR transmission between said
transceiver device and said host;
Framing rules for defining the form of transmitted (Tx)
and received (Rx) IR transmissions between said
transceiver device and said host; and
connection-less data defining rules for the IrLAP
layer; and
providing a Link Management Protocol (LMP) layer,
cooperating with said IrLAP layer, defining the
specification for establishing service-to-service connection
binding, and division of a reliable IrLAP connection to
multiple channels, using frame-by-frame multiplexing, and
comprising:
