Data communication system for writing or reading data to/from image forming apparatus at a remote distance and data communicating apparatus constructing such a system

摘要

In a remote registry system, an object of the invention is to read and write memory data as binary data. A memory access method is limited for a data read inhibit area or a write inhibit area. A facsimile apparatus of a remote registry system comprises an RMD communication unit, an RMD command analysis unit, a transmission and reception unit of memory data, a memory of binary data, a judging unit for judging whether an area is the read inhibit area in a memory area or not, and a judging unit for judging whether the area is the write inhibit area in the memory area or not.
