Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic incoming call system for a personal computer on a network.

[0002]

2. Description of the Related Art In recent years, personal computer (Personal Computer) communication via a LAN or the Internet has become widespread. . However, in order to improve this method that wastes energy resources by constantly turning on the power, a new automatic incoming call system has been proposed. For example, a published patent publication;
As described in detail in 297748 "Terminal device", when an incoming call is detected by the network control device, after turning on the personal computer, the interrupt processing unit of the communication processing program is loaded first before loading the OS. Then, by loading the OS, the received data can be received even if the system startup is not completed, and the received data is stored in a buffer provided for temporarily storing the data. In addition, there is a communication processing program preload method for performing processing such as transferring data received in the buffer to a file after completion of OS startup.

[0003]

In the above-mentioned conventional communication processing program preceding loading method, the interrupt processing section of the communication processing program is loaded first to give priority to data reception after the power is turned on. Since it takes several tens of seconds for the load processing and the self-test processing for the interface after the load, there is a problem that data transmission and reception times out depending on the protocol.

Further, since the loaded communication processing program cannot use the system call and the basic input / output function of the OS until the OS is loaded, the communication processing program must be provided with these functions on its own and the design man-hour is reduced. There was a disadvantage that it became larger.

An object of the present invention is to use a resume function of a personal computer to save the state of a memory for storing an OS and a communication processing program and a state of a CPU with low power during absence, and to receive a call through a network line. If there is, the system power supply is automatically turned on via the resume function, data is received by the communication processing program on the memory, and after the data reception is completed, the power is again turned off via the resume function by the communication processing program. Thus, it is an object of the present invention to provide a personal computer automatic call receiving system that can maintain a system with low power consumption during an absence and can receive data without a time delay due to a program load or the like at the time of an incoming call.

[0006]

The power supply is turned off except for a predetermined portion.

According to a second aspect of the present invention, in the power-off state of the first aspect, when a power restart request is received by a predetermined input method, the power of the personal computer is turned on via the resume means. Then, the received data stored in the data file is displayed on a screen provided in advance.

[0008] In a third aspect of the present invention, in an automatic personal computer termination system for a personal computer connected to a network via a network control device, an RS232 interface unit for transmitting and receiving data to and from the network control device via an RS232 interface. A called signal from the network controller corresponding to the incoming call from the calling side is transmitted to the R
