Description

Detailed Description of the Invention [Objective of the Invention] (Industrial Application Field) The present invention is directed to a computer that controls the display of a display device such as a CRT and the operation mode of a printer using an ESC sequence from a host computer. Regarding terminal devices.

(Japanese technology) Display devices such as CRTs whose display is controlled by an ESC sequence from a host computer, or computer terminal devices such as printers whose print operation mode is controlled, have a fixed ESC sequence that corresponds to the control. It is determined that Therefore, the analysis database for analyzing the ESC sequence is also set to a fixed value, and the ESC sequence sent from the host computer is analyzed based on the analysis database of the fixed value.
Manputer terminal device is controlled 6 (problem to be solved by the invention) In the above-mentioned terminal device of the United States and America, it is controlled by the ESC sequence from the host computer, but this ESC
In reality, the sequence is fixed based on the terminal device, and differs depending on the type of each terminal device.

Therefore, a host computer in which a seven-part application using the ESC sequence of a specific terminal device is executed has the disadvantage that it is difficult or impossible to use terminal devices other than that specific terminal device.

The present invention was invented in view of the above circumstances, and its purpose is to provide an extremely effective and appropriate computer terminal device that allows the ESC sequence to be set to any desired value.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides an ESC sequence analysis database in a computer terminal device, and performs ESC processing from a host computer by referring to this ESC sequence analysis database.
an ESC sequence analysis means for analyzing the sequence; and an ESC sequence analysis means for receiving update data from the host computer.
A first updating means for updating an SC sequence analysis database, and a tJIS2 updating means for receiving update data from a keyboard and updating the ESC sequence analysis database, so that the ESC sequence can be set to any one. It is characterized by what it did.

(Function) The computer terminal device can be set to any ESC sequence. (Example) Next, an example of controlling a display device as a device for controlling a computer terminal device will be described with reference to the drawings. FIG. 1 shows a block diagram showing the structure of the present invention, and 10 is an interface 7 for receiving data etc. from a terminal device according to the present invention and a host computer (not shown).

Update. 16 is a keyboard update data receiving program, and by executing this keyboard update data receiving program 16, update data of the ESC sequence analysis database 13 is received from the keyboard, and the ESC sequence analysis database 13 is updated. Next, the operation of the present invention will be explained.

FIGS. 2 to 4 show seven flowcharts showing the operation of the present invention, and the operation of the present invention will be explained with reference to these drawings. FIG. 2 shows the normal operation of analyzing the ESC sequence from the host computer and controlling the display. In step S1, data of the ESC sequence from the host computer is received. In step S2, the ESC sentence is analyzed. If it is determined in step S3 that the analysis is complete, the process advances to step S4. In step S4, it is determined whether the ESC sequence has been recognized. When the ESC sequence is recognized, the process advances to step S5, and in step S5 the ESC sequence is recognized.
Display control corresponding to the sequence is executed. If the resolution is not completed in step S3 or if it is not recognized in step S4, the operation returns to step S1.

Next, the ES is updated using updated data from the host computer.

& Explain the 7 low chart in Figure 3. In step S6, update data is received from the host computer. If the update data received in step S7 is determined to be end data, the operation ends. If it is determined in step S7 that the data is not the end data, the process advances to step S8. In step S8, the received update data is saved.
Next, in step S9, it is determined whether the updated data is complete. If it is determined in step S9 that the updated data is complete, the process proceeds to step S10, and in step 810, the ESC sequence analysis database 13 is updated with the updated data.

If it is determined in step S9 that the updated data is not complete, the process returns to step S6. Next, input the update data from the keyboard 12 to input Q and E.
The case of updating the SC sequence analysis database 13 will be explained with reference to the 7-row chart shown in FIG. 4. In step 811, input data from the keyboard is received. Next, the process advances to step S12, and in step 812 it is determined whether the input data on the keyboard is an end key.
If the end key is pressed, the operation ends. If it is determined in step 812 that the key is not an end key, the process advances to step S13. In step 813, the updated data from the keyboard is saved. Next, in step 814, it is determined whether the updated data is complete. If it is determined in step S14 that the updated data is complete, the process advances to step S15. In step S15, the ESC sequence analysis database is updated using update data from the keyboard. Note that if it is determined in step S14 that the update data is not complete, the operation proceeds to step S1.
Return to l.

As described above, the terminal device according to the present invention normally controls the ESC by executing the display control program 14 as shown in FIG.
The sequence analysis database 13 is referred to for analysis, and the display on the display device 11 is controlled. At any given point in time, the host update data receiving program 15 as shown in FIG. 3 is executed by inputting a special ESC sequence from the host computer, and the host update data receiving program 15 as shown in FIG. The keyboard update receiving program 16 is executed.

When the host update data receiving program 15 is being executed, the host update data receiving program 15 recognizes the data from the host computer as the update data of the ESC sequence analysis database 13 and executes the ESC sequence until the end trigger is -. The analysis database 13 is updated.

In addition, when the keyboard update data receiving program 16 is being executed, the keyboard update data receiving program recognizes the data from the keyboard as the update data of the ESC sequence input analysis database 13 until it takes one time to finish, and the ESC Sequence analysis database 13
Update.

[Effects of the Invention] According to the present invention, since the ESC sequence can be set to any value, it has an extremely significant effect that can be used even in application programs that only consider the ESC sequence of a specific terminal device. be.
