PROBLEM TO BE SOLVED: To provide an information communication system which uses a small mobile personal computer as a host, and which can communicate bidirectionally using a portable information communication device, and which can also use data commonly in between both. SOLUTION: An information communication system 100 is arranged, so that a host communication terminal device and a personal digital assistance device 2 can conduct bidirectional data communication therebetween, by selectively using any of wired and wireless functions. The personal digital assistance device 2 confirms whether it is able to communicate with the host communication terminal device 1 at intervals of a preset time. Only when the communication is enabled, will the system 100 execute synchronized processing operation between the host and personal digital assistance devices 1 and 2. |
