PURPOSE:To improve the processing efficiency, by adding a code which discriminates a control code to the head of a block of the control code of the data which is transferred from one device to the other, then discriminating the control code at the receiving side. CONSTITUTION:At a processing part 7, a discrimination code A is added to the head of a control code C of a data D which is extracted out of a file 8, and the data D is sent to a communication controller 4. A control part 5 receives the data and discriminates the code A for the transferred data within a buffer 3. Then the code A if discriminated is deleted, and the data D is extracted within the buffer 3. When the part 5 deblocks the data D, a control code C1 and a data d1 are sent to a terminal device 1 as the 1st block and with addition of transmission control characters STX and ETB. In the same way, the 2nd block B2 and so on are sent. Thus it is enough to discriminate only a kind of code A instead of for plural types of control codes C1-Cn. This improves the processing efficiency. |
