Abstract:
The initialization of the input/output counter at the initial situation in the process of controlling the input/output just before packet exchanging is implemented by a microprocessor part(10)(S1,S2). In case of receiving the data exchanging start signal from the packet exchanging main control unit(1), the input/output counter about the data storage block is increased(S3,S4). In case that the value of input counter which represents the data volume stored at the data storage block and that of output counter which represents the data volume read from the data storage block and emitted at the queueing state in the process of input/output right after the next packet exchanging is not same, after reading the packet data from the packet data storage block(5) and emitting to the serial communication line, and the output counter is augmented by receiving the packet emit signal(S6,S7).
