Abstract
A communication device includes a storage medium for storing a program and information used to detect any error in the program, to prevent the communication device from further abnormal operation when an error occurs in the stored program. The occurrence of an error in the program is detected by performing a calculation based on the stored program, and comparing the result of the calculation with the above-described information stored in the storage medium. A predetermined operation is further performed depending on the result of the comparison.
