Abstract
The present invention relates to a far-end control method with a security mechanism including a host transmitting an identification code through the PSTN (Public switched telephone network) to the I/O control device of the far-end. The I/O control device has a CPU to receive the identification code and judge whether the identification code matches with the predetermined value stored therein; if the identification code matches with the predetermined value, the mobile internet connection between the host and the I/O control device is activated to enable the host to mutually transmit information or signals with a far-end control device from the I/O control device through the mobile internet, and the connection will be disabled after the information or signal transmission is completed. Thus not only the damage caused by line occupied from the hacker invasion or error signal transmission is reduced, but also the cost and power consumption without connecting the mobile internet between these two ends all the time is reduced.
