Abstract

A method of executing communication programs in a modem apparatus. A plurality of communication programs used to perform data communication or facsimile communication are stored in an internal memory space (e.g., ROM) in a processor after they have been compressed. A communication program to be executed in ROM is decompressed and developed in a work area external to the processor (e.g., RAM). The developed communication program is then executed by the processor. The data decompression is performed according to an exclusive program decompression program or a program in the communication programs which is adapted to provide a data decompression function.
