PROBLEM TO BE SOLVED: To provide a communication terminal which can prevent a device from being unusable even when the device cannot normally be resumed after a program is downloaded, and can enhance the convenience. SOLUTION: This communication terminal is configured to download an updating program from a Web server 4 connected via a network 3 when a control part receives an instruction of downloading the updating program from a user terminal (DTE) 6 connected via a network, to store the program in a memory part, and to try to resume. Further, the communication terminal is configured to download a prior program from the Web server 4 when it is impossible to resume normally if trying to resume a preset number of times, to store the program in the memory part, and to resume. Also, the user terminal 6 is informed that the prior program has been restored. COPYRIGHT: (C)2009,JPO&INPIT
