<p>PURPOSE:To provide the data transmitter which guarantees the transmissivity of data and reduces burden to a CPU with simple additive circuits. CONSTITUTION:At the device to communicate communication data according to a step synchronizing system, a flag generating circuit 3 to select and generate several patterns among the combination of patterns which can not transmitted at all the kinds of transmission speed using the device, a flag detecting circuit 4 to detect those patterns on the reception side, and control signals and the communicating data can be transmitted by one communication circuit line regardless of the transmission speed of the communicating data are provided.</p> |
