Abstract

PURPOSE:To perform the test of an information processor despite a defect of a keyboard or the absence of the keyboard by providing a means to discriminate whether the keyboard is connected or not to the information processor. CONSTITUTION:A diagnosis program executes an initialization command via a keyboard 6 and a discriminating means 1 acquires the information on connection of the keyboard 6 according to whether or not an answer is received from the keyboard 6. Then the means 1 stores the presence or absence of connection of the keyboard 6 in a keyboard memory part 8 to complete its processing and delivers the control to a switching means 2. The means 2 extracts the data out of the part 8 via the means 1 to discriminate the start of an input/ output device 3 or an output device 4. Then either one of both devices 3 and 4 is started. In a connection mode of the keyboard 6, the data received from the keyboard 6 are stored in a keyboard data memory part 7 and the control is shifted to an executing means 5. While the means 2 starts the means 4 if the keyboard 6 is not connected.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an execution method of a diagnostic program for testing an information processing device.

[Conventional technology]

Conventionally, a diagnostic program for a device having a keyboard always requires an operator to input data from the keyboard when executing the diagnostic program, regardless of the connection state of the keyboard.

[Problem that the invention seeks to solve]

Executing the conventional diagnostic program described above always requires the operator to input data from the keyboard, regardless of the keyboard connection status, so if the keyboard itself is defective or there is no keyboard, the diagnostic program cannot be executed. It has the disadvantage that it is not possible to test the hardware functionality of the device.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for executing a diagnostic program that stores the keyboard connection state so that the diagnostic program can be executed even when the keyboard is not connected.

[Means for solving problems]

Next to the diagnostic program execution method of the present invention, a determining means for determining whether or not a keyboard is connected to the information processing apparatus, a keyboard storage section for storing connection information of the determining means, and inputting the connection information. a switching means for outputting switching information of the keyboard connection or non-connection, an input/output means for inputting switching information of the keyboard connection of the switching means and inputting/outputting data from the keyboard, and output data of the input/output means. a keyboard data storage section for storing the keyboard data, a table for storing the keyboard data in advance, and a table board for indicating a storage location of the table;
A pointer register for storing ink and switching information of the switching means for the keyboard not being connected are input, a table pointer stored in the table register is input, and the keyboard data on the table is retrieved based on the table pointer. output means for storing data in the keyboard data storage section stored in the input/output means and advancing the table pointer; The information processing apparatus is characterized in that it includes an execution means for executing a test of the information processing apparatus based on the retrieved data.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, and FIGS. 2 to 6 are execution flowcharts of each means 1 to 5 in FIG. 1.

Referring to FIG. 1, the embodiment of the present invention includes a determining means 1, a switching means 2, an input/output means 3, an output means 4, an execution means 5,
It is composed of a keyboard 6, a keyboard data storage section 7, a keyboard storage section 8, a table register 9, and a table (keyboard data) 10.

Next, the present invention will be explained with reference to the drawings.

First, the diagnostic program executes an initialization command to the keyboard, and depending on whether there is a response from the keyboard 6,
The determining means 1 obtains the information on the keyboard connection (step 21 in FIG. 2), stores the presence or absence of the keyboard connection in the keyboard storage section 8 (step 22 in FIG. 2), completes the process, and passes control to the switching means 2. .

The switching means 2 retrieves the data stored in the keyboard storage section 8 by the determining means 1 and activates the input/output means 3 (FIG. 1A'), but does not activate the output means 4 (FIG. 1B'). It is determined whether the input/output means 3 or the output means 4 is activated (step 31 in FIG. 3).
2).

When the keyboard 6 is connected (connected to A in FIG. 1), the input/output means 3 is activated by the switching means 2.
(A' in Figure 1) Obtains the data entered by the operator on the keyboard 6 (Step 41 in Figure 3), and stores the data from the keyboard in the keyboard data storage section 7 (Step 42 in Figure 3). , transfers control to the execution means 5.

On the other hand, if the keyboard 6 is not connected (connected to B in Fig. 1), the switching means 2 activates the output means 5 (B in Fig. 1).
'). The activated output means 5 retrieves the table pointer indicating the storage location of the table stored in advance in the table register 9 as the data of the keyboard 6 (FIG. 5 STEP 51), and outputs the retrieved table pointer. Based on this, the keyboard data on the table 10 is obtained, and the obtained keyboard data is stored in the same keyboard data storage section 7 where the input/output means 3 stores (step 53 in FIG.
)do.

Since the data on the table has been used, update the pointer to the location where the next keyboard data is stored (step 54 in Figure 5), store the new pointer in table register 9 (step 55 in Figure 5), and execute Control is passed to means 5.

The execution means 5, which has been given control from the input/output means 3 or the output means 4, is unaware of whether the data is from the keyboard 6 stored in the keyboard data storage section 7 or the data stored in the table 10 in advance. In step 61) of FIG. 6, the data is retrieved as data from the keyboard 6.
Based on the data, a diagnosis of the device is performed (step 62 in FIG. 6). If the device test is executed (Step 6 in Figure 6),
In step 2), when a plurality of key data are required, the processing after the switching means 2 is repeated to diagnose the device.

〔Effect of the invention〕

As explained above, the present invention first checks the information as to whether a keyboard is connected, and if the keyboard is connected, performs vS@ of the device based on the data obtained from the keyboard input by the operator. is not connected, the test program runs to test the device based on predetermined data without operator intervention, so even if the keyboard is defective or there is no keyboard, the device can be tested. It has the effect of being able to carry out.
