PURPOSE:To reduce a load for transmission processing, and also to reduce a load for preparing software by detecting automatically the head of a transmission text, when transmitting information to an from a program loader, and comparing it witn an STX code. CONSTITUTION:When a reception interrupting signal 6A is inputted to a controlling circuit 1-1 through an interruption detecting circuit 1-2 from a transmitting device 6, the received data is read out by one type from the transmitting device 6, in a received data readout circuit 1-3 by its control signal, and said data is compared with an STX code by a text head detecting circuit 1-4. When they coincide with each other, a coincidence signal 14A is sent to the controlling circuit 1-1, an STX detection request flag is reset, an operation of a data storing gate is permitted, and a receiving text is written in a received data store memory 5-4. |
