Abstract

PURPOSE:To enable data communication between information processors with different attribute, without remolding an existing information processor, by conversion processing of information in a modulation and demodulation device. CONSTITUTION:As the information transmitted from an information processor via an interface control section 10, net information 6 and conversion processing instruction information 7 are included, the instruction information 7 is interpreted at an instruction interpretation section 12, and selector switches 18, 19 are controlled based on the result of interpretation. One conversion is made for the succeeding net information 6 as conversion into dot pattern information, conversion of the ASCII code to the EBCDIC code, or nonconversion, and the infomation is transmitted to a signal transmission line via a signal transmission line control section 11. The information with the conversion processing instruction information inputted from the signal transmission line to the signal transmission control section 11 is interpreted at an instruction interpreting section 13, changeover switch sections 20, 21 are controlled, and one of processing sections 16...17 depending on the instruction is selected for the conversion processing.
