【発明の詳細な説明】
本発明は多数の端末装置を有するデータ処理システムに
おいて、端末装置の仕様変更や制御プログラムの改版が
、センタ側の保守のみで管理できるようにした端末装置
制候方式に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a terminal device climate control system that allows changes in specifications of terminal devices and revisions of control programs to be managed only by maintenance on the center side in a data processing system having a large number of terminal devices. .
従来より端末装置の仕様変更は制御プログラムを変更す

属のフレキシブルディスク装置等からロードして利用さ
れるか、又は不揮発性の固定記憶装置（ＲＯＭ）中に格
納されて利用されるかのいずれかである。Conventionally, specifications of a terminal device can be changed by changing the control program, but the control program is either loaded from a flexible disk device attached to the terminal device or stored in a non-volatile fixed storage device (ROM). Either it is stored inside and used.
従つて前者の場合には、フレキシブルディスク媒体を端

る。Therefore, in the former case, specifications cannot be changed unless the flexible disk medium is delivered to the location where the terminal device is installed, and it is troublesome to distinguish and manage the old disk from the new disk.
There was also a risk of misuse. Also, in the latter case, the ROM
It had to be replaced and had the same drawbacks. The present invention is a terminal control system that solves these drawbacks, and will be explained in detail below with reference to the drawings. The figure is a block diagram of an embodiment of the present invention.

る。In the figure, TMI, TM2, . . . are terminal devices that have a display and a keyboard as well as a control memory CS that stores a control program. A part of CS is iPL (
Although the minimum resident program RP for performing initial program loading etc. is prepared in a non-volatile ROM, the other parts are constructed from a rewritable RAM. The terminal processor TP also has an identification code I unique to the terminal.
It has means IDG for emitting D. This IDG is, for example,
Automatically by hardware when the terminal starts, such as when the power is turned on.
Or controlled by the above RP. CCP is a communication control processing device, which has a large number of terminal devices TMI, TM2, etc.
・Connect with the central processing unit CPU in a time-sharing manner. The CCP has a terminal control file TCF, and the TCF has multiple terminal control programs TCPI, TCP2, 1...
It also has a correspondence table TBL between each terminal and each TCP. TCP varies depending on the model of the terminal, and even depending on the contract provision function of the same model. Naturally, the same TCP may be used for different terminals. Next, to explain the operation, when the terminal device is powered on, the hardware performs RP.
At the same time, the IDG sends information to the CCP.

端末として使用できることになる。The CCP indexes the TBL to find the TCP corresponding to the sent ID, and transfers it to the CS of the terminal. The RP controls writing to the CS during the transfer. After that,
The terminal is controlled by the transferred TCP. T.C.
When a version of P is updated, the new TCP is replaced with the old TCP.
or add it to the TCF and update the TCP number corresponding to the TM that should provide the new version in the TBL. Furthermore, in response to a request for increased functionality from the terminal side, the center side only needs to rewrite the TBL. Furthermore, if a plurality of IDs are assigned to one terminal and any one of them can be sent, one terminal can be used as a terminal with different functions depending on the purpose.
以上の如く本発明によれば、数百台も多数の端末装置を

ＯＭを交換しにＣＥを派遣する等の必要が無くなる。As described above, according to the present invention, even in a system having hundreds of terminal devices, it is possible to easily change the specifications of any terminal or upgrade the version by simply maintaining and managing the TCF on the center side, and it is possible to easily deliver flexible disks. Tari, R
There is no need to dispatch a CE to replace the OM.
