JPS63213025A - Automatic registering system for code conversion table of peripheral equipment - Google Patents

Abstract

PURPOSE:To enable a system producer to perform the standard processing without knowing well the details of a code conversion table, by registering automatically a standard code conversion table of a peripheral device into a system if the code conversion table corresponding to the peripheral device is not registered into the system. CONSTITUTION:If a registered code conversion table is not available, a code conversion table name recognized at the time of initialization is set at a registered code conversion table name. Thus a relevant code conversion table is produced at a code conversion table main body part 6. While an automatic code conversion table register mechanism 4 performs nothing as long as a registered code conversion table is available and also equal to that obtained in an initialization state. If the registered table is not equal to said one, the mechanism 4 issues the preference to the registered table if this table is available to the corresponding peripheral devices 11-13. Otherwise a control table 5 and the part 6 are replaced via the conversion table recognized at the time of initialization.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application: The present invention relates to an automatic peripheral device code conversion table registration method. The present invention relates to an automatic peripheral device code conversion table registration method that can simplify system generation by registering and replacing code conversion tables according to the following.

Conventional technology Conventionally, registration of this type of peripheral device code conversion table is
Either the system is fixedly specified using system generation parameters or other means when the system is generated, or both of these methods require the person creating the system to be aware of what types of peripheral devices are connected to the system. Therefore, it was necessary to register the seed conversion table required by the peripheral device in the system.

Problems to be Solved by the Invention In the conventional peripheral device code conversion table registration method described above, the person who generates the system does not know what kind of code conversion table can be used by the peripheral device connected to the computer system. Since it requires thorough knowledge, it has the disadvantage that errors are likely to occur when generating the system.

Additionally, the code conversion table needs to be added or changed when peripheral devices are added or changed, but with the conventional method described above, it is easy to forget to add or change the code conversion table. During operation, the peripheral devices may malfunction or not operate at all, so there is a drawback that errors during system generation have a large effect.

The present invention has been made in view of the above-mentioned conventional situation,
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a new peripheral device code conversion table automatic registration method that makes it possible to eliminate the above-mentioned drawbacks inherent in the conventional technology.

Means for Solving the Problems In order to achieve the above object, the peripheral device code conversion table automatic registration method according to the present invention provides a system initialization operation in a computer system equipped with a peripheral device that requires a code conversion table. Sometimes, there is a means to automatically recognize the type of standard code conversion table corresponding to the peripheral device, and if the code conversion table corresponding to the peripheral device is not registered in the system, the standard code conversion table for that peripheral device. is registered in the system, and if it is already registered in the system, the code conversion table registered in the system is used if it is within the range that can be used by the peripheral device actually connected to the computer system. If the code conversion table is outside the range that can be used by a peripheral device actually connected to the computer system, it has means for re-registering it in the system with a code conversion table that is normally used by that peripheral device.

Embodiment Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

When all the operations of the automatic code conversion table recognition mechanism 3 are completed, the automatic code conversion table recognition mechanism 3 starts the automatic code conversion table registration mechanism q. The code conversion table automatic registration mechanism operates as follows based on the contents of the code conversion table management table 3.

If a registered code conversion table does not exist, set the code conversion table name recognized at the time of initial setting to the registered code conversion table name, and generate the code conversion table in the code conversion table main unit 6. do.

If a registered code conversion table exists and it is the same as the code conversion table name recognized at the time of initial setting, the code conversion table automatic registration mechanism does nothing.

If a registered code conversion table exists and its name is different from the code conversion table name recognized during initial setup, the code conversion table automatic registration mechanism will automatically match the registered code conversion table to the corresponding peripheral device. ／／、／
, 2. If /J is possible, do nothing, giving priority to the registered code conversion table.

However, peripheral devices //, /2. /3 is exchanged, and if it is determined that the corresponding peripheral device //, l, 13 malfunctions in the registered code conversion table, the code conversion table is changed using the code conversion table recognized at the time of initial setting. The management table 3 and code conversion table main body part 6 are updated.

By performing the above-described operations by the code conversion table automatic registration mechanism, standard measures are always taken when the system configuration is changed, even if the system creator does not specifically designate it.

It also shows that even if the system creator makes an incorrect specification, the correct standard action is always taken.

As described in detail, according to the present invention, standard measures are automatically taken even if the system creator is not familiar with the details of the code conversion table, reducing the burden on the system creator. You can get the effect of being lightweight.

Furthermore, even if the system creator specifies an incorrect code conversion table, the correct processing in the standard case is automatically taken, so errors made during system creation do not have a major impact.
