Abstract: An infrared communication apparatus and method enabling data communication with a receiving device, regardless of a protocol with which the receiving device is compatible. A transmitting unit transmits a first packet to inquire whether a receiving device is compatible with a first protocol and transmits a second packet to inquire whether the receiving device is compatible with a second protocol, to the receiving device at least once, and transmits a plurality of third packets to inquire whether the receiving device is compatible with a third protocol, to the receiving device. A receiving unit receives a response packet indicating a protocol with which the receiving device is compatible, from the receiving device having received the first packet, the second packet, and the plurality of third packets. A data transmitting unit transmits data to the receiving device, based on the protocol indicated by the response packet received by the receiving unit.

Abstract: The communications device of the present invention performs an authentication with the device at the other end automatically or through a simple operation, independently of an authentication scheme supported by the device at the other end. A communications device includes: a connecting section for establishing a connection with the other communications device according to the IrSimple scheme; an authentication section for performing an authentication by the IrSimple scheme; a connecting section for establishing a connection with the other communications device according to the IrDA scheme, an authentication section for performing an authentication according to the IrDA scheme; and a protocol switching section for causing the connecting section to initiate a connection and causing the authentication section to perform an authentication, when an authentication by the authentication section is unsuccessful.

Abstract: A communications device includes: an IrDA frame detecting section 202, an IrSimple frame detecting section 201, and a transfer rate control section 230. The IrDA frame detecting section 202 detects a first predetermined frame based on pulses detected in an incoming response signal at first predetermined intervals. The IrSimple frame detecting section 201 detects a second predetermined frame based on pulses detected in the incoming response signal at second predetermined intervals. The transfer rate control section 230 determines that the transfer rate of the response is equal to the first transfer rate if the IrDA frame detecting section 202 detects the first predetermined frame and determines that the transfer rate of the response is equal to the second transfer rate if the IrSimple frame detecting section 201 detects the second predetermined frame.

Abstract: A communications device 1a is a primary station which communicates with a secondary station. The communications device includes a communications protocol analyzing section 160a and a protocol control section 110. The section 160a is capable of receiving both a first response to the first-connection-routine command and a second response to the second-connection-routine command. The first and second responses are distinguishable from each other. The section 160a determines by analyzing an incoming response whether the response is the first response or the second response. The section 110 connects to the secondary station using the first protocol if the communications protocol analyzing section 160a determines that the response is the first response and using the second protocol if the communications protocol analyzing section 160a determines that the response is the second response.
