An interface communication standard sensing device having a CPU for setting a circuit, comprising: a switching transistor connected between pin 8 of a connection jack connected to the serial driver and a level sensing port of the CPU, thereby switching the switching operation of the switching transistor. The interface communication standard automatic sensing device capable of serial communication according to the PC model to communicate according to the present invention, the interface communication standard automatic detection method of the present invention is detected by detecting the data of pin 8 of the connection jack by interrupting at an arbitrary time interval. Any number of times according to the first step A second step of repeating the first step while interrupting the number, and if a data level is detected in the first step, it is determined to be connected to a Macintosh PC, and outputs a logic 0 to the CPU according to the transfer speed of the connected PC model. When the third step is interrupted a predetermined number of times or more in the second step, it is determined that the connection with the IBM PC model, and the fourth step for outputting logic 1 to the CPU in accordance with the transmission speed of the connected PC model.

본 발명은 스위치 대신 트랜지스터를 적용함으로써 원가절감에 효과적이며 사용자가 PC의 기종을 선택하는 불편함을 없앤다.The present invention is effective in cost reduction by applying a transistor instead of a switch, and eliminates the inconvenience of the user selecting the model of the PC.
