INFORMATION PROCESSOR HAVING INFRARED COMMUNICATION FUNCTION AND ITS CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide an information processor which smoothly transfers a processing result that is acquired with application execution or transfer data such as an HTML(hypertext markup language) file that is acquired from a server according to a TCP/IP(transmission control protocol/internet protocol) protocol to an external device (PDA) by using an infrared communication function and its control method. SOLUTION: An information processor periodically accesses a prescribed server machine (e.g. a web server) on a network such as an internet and acquires a desired file (e.g. an HTML file). The file acquisition operation is ventured to be executed regardless of the operation of an infrared light transmitting and receiving part. In other words, the information processor always tries to cache the latest download data for a PDA. As a result, only by setting a PDA as an external device to an infrared communication mode and holding the information processor up in an area where a station can be found, the connection between them is established and the latest data is received.
