PURPOSE:To execute the reconversion to binary data with a data input/output device inputted by describing an ASCII code by providing a logic circuit to convert the data of an ASCII code description to the binary data in an input/ output device. CONSTITUTION:Data 4 are assumed to be the 10101011(OABH) of binary data and thought to transfer to an information processor 1 including the input/output device from an information processor 2. When the data 4 are desired to be transferred and the data; OABH, is already reserved by a protocol, the data 4 cannot be transferred as it is. Therefore, the higher order data of the data 4 may be transferred to data 2, the lower order data of the data 4 are transferred to data 3 by converting them to an ASCII code, the data 2 comes to be 41H, the data 3 comes to be 42H, data 1 are the special data to show that the binary data are converted to the ASCII code and set to a register 112b for setting the special data. |
