CONSTITUTION:A transmitting destination equipment T to receive a starting telegraphic message SM checks a collating code ID and further, when the code is satisfactory after the error checking is executed, a confirming telegraphic message ACK is returned. Next, a designating telegraphic message IM is sent from a transmission equipment C, and out of this, head and end addresses AS and SE designate the address to store a program and data transmitted into a memory space MS1 of a RAM6. The transmitting destination equipment T to receive the designating telegraphic message stores the contents to a prescribed place AA in the RAM6 and returns the confirming telegraphic message ACK. The transmission equipment C transmits the data of the prescribed length by sending a series of a contents telegraphic message DMj and the constitution of respective contents telegraphic messages DMj may be simple with the prescribed unit length, for example, a data block Dj of 256B as a main body. |
