An information service terminal communication adapter controls a connection state between an information service terminal and a communication line by means of a connection state control section. A diagnostic signal transmitting section outputs to the information service terminal a diagnostic signal for judging whether or not a predetermined program normally runs. A response discriminating section receives a response signal from the information service terminal corresponding to the diagnostic signal transmitted by the diagnostic signal transmitting section, and discriminates whether or not the predetermined program normally runs. A terminal restart section outputs a signal for restarting the predetermined program to the information service terminal in the case where the response discriminating section discriminates that the predetermined program does not run normally. In this manner, a communication adapter side can detect speedily that a program for information processing stops on the information service terminal side, and automatically recovers the program from such stoppage. <IMAGE> |
