DETAILED DESCRIPTION OF THE INVENTION

[0001]

2. Description of the Related Art When a data processing device having a data communication function and operable as a terminal device is connected to a mainframe via a public line, and data is exchanged between the two, the data processing device is used. If you leave your phone connected to the line, your phone bill will be wasted. Therefore,
In order to save on telephone bills, such devices are provided with an automatic timeout function in the point-to-point communication protocol, which automatically disconnects the device from the line when the device has been idle for a certain period of time. I have. For example,
When a state where neither data input from the keyboard to the data processor nor data input from the mainframe via the public line continues for a certain period of time, an automatic timeout function is activated, and the data processor is disconnected from the line. And the execution of the screen control program is forcibly terminated.

[0002]

However, in the conventional data processing apparatus as described above, when the unused time exceeds a certain time, the apparatus is suddenly disconnected from the line and the execution of the screen control program is stopped. For example, if the user has inadvertently activated the automatic timeout function while interrupting data entry work for another task, all data entered so far will be lost. Problem.

[0003] An object of the present invention is to provide a data processing apparatus which solves such a problem and makes it possible to prevent input data from being lost due to carelessness of a user.

[0004]

The object of the present invention is to provide a data processing device having a data input device and a data communication control device for transmitting and receiving data via a line, wherein the data processing device is connected to a line. When the connection time is set to a state in which no data is input from any of the data input device and the communication control device when connected to
If the operation timeout period is exceeded, the
Has a function of disconnecting the line that is connected,
This is achieved by a data processing device comprising: means for displaying the duration corresponding to a timeout time; and means for notifying when the duration becomes equal to a preset time. You.

[0005]

When the user interrupts the data input operation by the data input device to perform another job, the interruption time
Is displayed corresponding to the automatic timeout period . Further, when the interruption time becomes equal to the time preset by the user, this is notified, for example, by a buzzer. Therefore, it is possible to prevent the interruption time of the data input operation from exceeding the automatic timeout period due to the carelessness of the user, disconnecting the data processing device from the line, and losing the data input up to that time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 2 shows a block diagram of a data processing device according to the present invention. In FIG. 1, an input device 1 is composed of a keyboard having character keys and function keys.
It has a function to emit a warning sound by a buzzer. The display device 2 is constituted by a CRT and displays characters input from the input device 1 and guide messages when using various utilization functions of the data processing device. Functions used by the data processing device include a terminal emulator, an editor, a document processor, an electronic mail, and the like. External storage device 3
Is for storing a program, data, an automatic timeout function setting file, and the like. The internal storage device 4 is for temporarily holding data read from the external storage device 3 and the like. The communication control device 6
It is connected to a mainframe or another data processing device through a public line, and transmits and receives data through the line.
The control device 5 controls the operation of each device described above.

Next, the operation of the data processing apparatus according to the present invention will be described with reference to the flowchart of FIG. In this device, as shown in FIG.
At the bottom of the screen, the set time of the automatic timeout and the unused time of the device are displayed in minutes. In the figure, a is the set time of the automatic timeout, and b is the unused time.
In this embodiment, the automatic timeout period is set to 20 minutes.

When a predetermined operation is performed on the input device 1, a program is started, and the unused time notification method setting file is read from the external storage device 3 and stored in the internal storage device 4 (step S11). The unused time notification method setting file contains data indicating the automatic timeout setting time and data indicating the number of seconds between the automatic timeout setting time and the program unused time when the buzzer sounds. I have. Here, "use of no program" refers to a state where neither a command or data input by a user to the data processing apparatus nor data input via a line is performed.

In step S12, "20" is displayed on the display device 2, and in step S13, 0 is substituted for variables T0 and T1 for initialization. The variable T1 is for storing the non-use time in minutes, while the variable T0 is for use in processing for updating the display time every minute. After initializing these variables, it is checked whether or not T1 is greater than T0 (step S14). In this case, since the result is "NO", the process proceeds to step S15, and 0 is displayed as the unused time. I do. Next, in step S16, the value of the variable T1 is substituted for the variable T0 (in this case, the value of T0 becomes 0).
1 (step S17).

Next, it is determined whether the buzzer should be sounded by referring to the non-use time notification method setting file (step S).
18) In this case, since the determination result is “NO”,
Proceed to step S20. Here, it is checked whether or not T1-T0 is greater than 1. In this case, the values of the variables are all 0.
Therefore, the process returns to step S14, and the same processing is repeated. In the above processing, if the result of the determination in step S18 is "YES", the flow proceeds to step S19 to sound a buzzer.

Every time the non-use time exceeds one minute, step S
Since the result of the determination at step 20 is “YES”, step S
After proceeding to 21, the new non-use time is displayed on the display device 2, and then in step S22, the value of the variable T1 is substituted for the variable T0, and in step S23, it is determined whether or not T0 has exceeded the set value of 20 (minutes). Is determined. Until the unused time exceeds 20 minutes, the processing from step S14 to step S23 is repeated.

If the apparatus is left unattended and the unused time exceeds 20 minutes, the result of the determination in step S23 becomes "YES", so that the connection with the public line is disconnected and the execution of the program is stopped. .

The user can arbitrarily set the timing at which the buzzer sounds by changing the data written in the non-use time notification method setting file.
5 seconds before the automatic timeout time, 10 seconds before, 30 seconds before,
It can be set to 120 seconds before or 180 seconds before.

The present invention can be applied to a personal computer (particularly, a notebook computer using a battery), a word processor, a calculator, an electronic organizer, and the like.

[0015]

As described above, the data processing apparatus according to the present invention has a time duration in which no data is input from either the data input device or the communication control device when the data input device is connected to the line. Automatic timeout time
And a means for notifying when the continuation time is equal to a preset time, so that the interruption time of the data input operation is automatically set due to the carelessness of the user. Exceed the timeout period,
It is possible to prevent the data processing device from being disconnected from the line and losing data input so far.
