Abstract

통신 장치의 송신 버퍼가 버퍼 풀 상태로 빠져들지 않는 통신 장치 및 통신 방법을 제조 비용의 상승을 수반하지 않고 제공하는 것을 목적으로 한다.It is an object of the present invention to provide a communication device and a communication method in which a transmission buffer of the communication device does not fall into a buffer pool state without involving a rise in manufacturing cost.

호스트 컴퓨터(1)로부터 수신한 커맨드를 버퍼링하는 수신 버퍼(431)과, 수신 버퍼(431)에 버퍼링되어 있는 커맨드를 처리하여 답신 데이타를 생성하는 CPU(41)과, CPU(41)에 의해 생성된 답신 데이타를 버퍼링하는 송신 버퍼(432)와, 송신 타이밍에 있어서, 송신 버퍼(432)에 버퍼링되어 있는 답신 데이타를 호스트 컴퓨터(1)로 송신하는 통신 포트(44)를 구비하고, CPU(41)이 호스트 컴퓨터(1)로의 데이타 송신을 필요로 하는 커맨드를 처리한 경우에 수신 버퍼(431)에 버퍼링되어 있는 커맨드에 대응하는 답신 커맨드만을 송신 버퍼(432)에 버퍼링시키며, 송신 타이밍에 있어서, 송신 버퍼(432)에 버퍼링되어 있는 답신 커맨드와 그것에 대응하는 데이타로부터 송신 데이타를 작성한다.Generated by the CPU 41 and the reception buffer 431 for buffering the command received from the host computer 1, the CPU 41 for processing the command buffered in the reception buffer 431 to generate the reply data. A transmission buffer 432 for buffering the returned reply data, and a communication port 44 for transmitting the reply data buffered in the transmission buffer 432 to the host computer 1 at the transmission timing, and the CPU 41. In response to a command processing a command requiring data transmission to the host computer 1, only the reply command corresponding to the command buffered in the reception buffer 431 is buffered in the transmission buffer 432. Transmission data is created from the reply command buffered in the transmission buffer 432 and the data corresponding thereto.
