Abstract

PURPOSE:To reduce a set-up time for an operation at the time of executing an immediate operation, by performing a data communication without loading a data communication program from a file unit, when the data communication is required immediately after the leading of a power source. CONSTITUTION:In case of setting a switch 4 at a usual mode, a CPU 1 loads an operation system, such as a DOS, etc., from a file unit, and stores it on a main memory 2a. In case of setting the switch 4 at a communication mode, the CPU 1 reads out the data communication program residing in the memory 2a, and executes the data communication. Hereinafter, the operation corresponding to an operation mode is performed at every switching of the switch 4. For example, at the time of switching the switch 4 from the communication mode to the usual mode, the CPU 1 detects the fact, and after loading an application program from the file unit as necessary, and storing it on the main memory 2a, the CPU executes the program.

FIG. 3 is a block diagram of such a data communication system. In the figure, a personal computer 8 is connected to a communication line via a modem 9 and a network control unit 10. Here, the power supply of the illustrated system is turned on and off as follows. First, after turning on the power of the personal computer 8, in order to enable effective operation of the personal computer 8, an operation system (O8) such as a disk operation system (DO8) is connected to the personal computer via a file device such as a floppy disk device (FDD) (not shown). 8's main memory and execute it. Application programs for further communication (network control program, multi-function telephone function program, data communication protocol, etc.)
is loaded from the file device into main memory. Thereby, data communication becomes possible after the personal computer 8 is powered on.

(Problem to be Solved by the Invention) However, in the conventional power supply system described above, after the power is turned on, the operating system is first loaded from the file device, and then the application program for data communication is loaded from the file device. Because of this configuration, there is a problem in that it takes a long time (several tens of seconds or more) for data communication to become possible after the power is turned on.

Therefore, an object of the present invention is to solve the above-mentioned problems, shorten the time required until data communication becomes executable after power-on, and provide a time-efficient power-up method for small electronic devices. do.

(Means for Solving the Problems) The present invention relates to a method for powering up electronic equipment connected to a communication line via a communication data modulation/demodulation device and a network control unit.

The present invention provides a method for powering up an electronic device as described above, in which the electronic device includes a non-volatile memory that stores information necessary for executing data communication, and a communication mode that executes data communication immediately after power is turned on. , and a switch for switching between and setting a normal mode in which the application program can be executed after the power is turned on.

When the power is turned on, if the communication mode is set, data communication is executed according to the contents in the memory,
When the normal mode is set, the application program is executed after loading the operating system from the file device within the electronic device.

(Function) For example, when the power is turned on and the communication mode is set, the information stored in memory necessary for data communication (for example, network control program, multi-function telephone function program, data communication data communication is performed according to the protocol (e.g. protocol).

On the other hand, when the power is turned on and the normal mode is set, the application program is executed after loading the operating system from the file device. In this way, when data communication is performed immediately after power is turned on, data communication can be performed without loading a program from the file device, so time efficiency can be improved.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. The illustrated configuration illustrates the main configuration of the personal computer 8 described above. Although not shown in FIG. 1, the personal computer shown in FIG. 1 is connected to the communication line 11 via the modem 9 and network control unit 10 shown in FIG.

In FIG. 1, 1 is a central processing unit (hereinafter referred to as CPU), 2a is a main memory, and 2b is an application program for data communication (network control program, multifunction telephone function program, and data communication protocol) and data communication time. A non-volatile memory that stores the minimum system programs necessary for the operation of a personal computer. 3 is an engineering 0 processor (hereinafter referred to as IOP)
, 4 are switches for switching and setting a communication mode in which data communication is executed immediately after power is turned on, and a communication mode in which application programs other than data communication can be executed after power is turned on. 5 is a file unit that stores an operation system such as DO8, various application programs, and the like. 6 is a power supply unit that supplies power to each part of the device, and 7 is a power on/off switch.

Next, the operation of this embodiment will be explained with reference to the operation flowchart 1- at power-on of this embodiment shown in FIG.

First, the power supply unit 1-6 is turned on by turning on the switch 7 shown in FIG. 101).

Here, CPU 1 monitors the state of switch 4 (step 102). When the switch 4 is set to the normal mode in step 102, the CPU 1 loads an operating system such as DOS from the file unit 5 and stores it in the main memory 2a (step 103). Subsequently, the CPU 1 loads the application program from the file unit 5, stores it in the main memory 2a, and executes it (step 104). On the other hand, when the switch 4 is set to the communication mode in step 102, the CPU sequentially loads and executes the data communication program resident in the memory 2a. Data communication is thereby executed. After that, switch 4 is switched,
Operate in the corresponding operating mode. For example, when switch 4 is switched from communication mode to normal mode, CPU
If 1, this is detected, and if necessary, the application program is loaded from the file unit 5, stored in the main memory 2a, and then executed. however,
At this time of loading, if DO8 has been loaded previously, there is no need to load DO8 again.

Furthermore, when the main memory 2a switches from the communication mode to the normal mode, it retains the data immediately before switching to the communication mode, so unless a new application program is loaded, the main memory 2a will operate according to the retained contents. Execute.

One embodiment of the present invention has been described above. In the above embodiment, the data communication program is stored in the memory 2b, but it may be configured to reside in the main memory 2a. Furthermore, in this case, among the data communication programs, the minimum system program necessary for the personal computer may be stored in advance in the file unit 5, and only this program may be loaded when the power is turned on, thereby improving time efficiency. be able to.

(Effects of the Invention) As explained above, according to the present invention, when it is necessary to perform data communication immediately after turning on the power, data communication can be performed without loading a data communication program from the file unit. Therefore, it is possible to shorten the operation preparation time when executing an immediate operation.
