INFRARED COMMUNICATION ADAPTER

摘要

It is to provide an infrared communication adapter which can carry out a data exchange with an external equipment having an infrared communication interface even though a portable telephone does not have an infrared communication function. The infrared communication adapter comprises a portable telephone side connecting section 4 for transmitting a serial data supplied from the portable telephone by connecting an external communication interface of the portable telephone; an infrared communication interface 3 for carrying out a data communication with the external equipment in accordance with the infrared communication protocol, wherein in order to transmit the data supplied from one communication interface to the other communication interface, the adapter analyzes a communication protocol of the communication interface disposed on the data supply side and carries out an RS232C emulation internally to transmit the data by converting the analyzed communication protocol into a communication protocol corresponding to a communication interface disposed on the data receive side. <IMAGE>
