PURPOSE:To attain ease of application of the titled system to an existing object device to be controlled by providing a program in response to the communication rule of said device to realize the independent communication rule at each line. CONSTITUTION:Memory sections 1-n in a memory 23 are provided independently and freely replaceably and each of them consist of one character transmission end interruption processing program A, one character reception interruption program B and one character string transmission/reception management program C. The program A of each memory section 23 starts its operation with one character transmission end signal interruption of a channel to which the memory section is connected and transmits one character to the channel. An interruption occurs from the control object device when the reception is finished, the end of reception is reported by the program B of the channel and the interruption of the next character is awaited. The transmission of one character string is finished sequentially in such a way and the program C completes the transmission/reception of the character string through the interruption. Thus, the memory section 23 is operated in parallel to attain the transmission/reception of the signal with the object device to be controlled. |
