Abstract

The method for improving the convenience of terminal operation comprises the following steps: selecting the screen information on the configuration initial screen; discriminating the outputted screen (color or monochrome); determining whether the screen attribute is changed or not; designating each screen attribute (normal, underline, reverse, etc) for wanted color; discriminating whether the specific attritue value transmitted from the host corresponds to the interval of the screen attribute value; outputting the attribute value as the designated color; designating the next attribute transmitted from the host, followed by converting the attribute value to the initial value.

The present invention relates to a screen attribute selection method of a display terminal.

In the related art, a display terminal (personal computer or dedicated terminal having an emulation function) has a problem in that the representation of the screen is limited according to a command of a host computer. For example, the IBM® 5250 terminal cannot display as much color as a user wants. Only a screen by a command of a host computer is displayed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problem, and an object thereof is to provide a method for changing and using screen firing according to a user's intention regardless of a command of a host computer.

In order to achieve the above object, the present invention provides a CPU for controlling a terminal system, a system memory and I / O buffer means connected to the CPU through a system bus, and an I / O buffer means connected through an I / O bus. A command memory means and data memory means connected to the BCP and connected to the I / O buffer means via an I / O bus, a latch connected between the BCP and the data memory means, a host connected to the BCP and a host A screen property selection method of a terminal system comprising a line interface means connected to a TWNAX cable connected to a computer, the method comprising: a first step of selecting screen information on a configuration initial screen; an output screen (color or monochrome) ) The second step of determining), the third step of determining whether or not to change the screen attribute, the desired color of each screen attribute (normal, underline, reversed, flickering, emphasis, etc.) A fourth step of selecting and specifying a value; and a fifth step of determining whether an adopted specific attribute value transmitted from the host falls within the screen attribute value range, and determining which attribute specifically corresponds to the specific attribute value. In the sixth step of processing the output in the color specified in the step, the next attribute from the host is specified to be adopted, the attribute value is converted to the initial value and is performed by the seventh step of repeating from the fifth step described above. It is done.

1 is a schematic block diagram of a system to which the present invention is applied, in which 1 is a central processing unit (hereinafter, simply referred to as 'CPU'), 2 is a system bus, 3 is a system memory part, and 4 is an input / output (I) Buffer part, 5 and 6 are input / output (I / O) buses, 7 is Biphases Communication Processor (BCP), 8 is instruction memory part, 9 is data memory part, 10 is latch, 11 is line ( line) represents each interface part.

As shown in the figure, a system to which the present invention is applied includes a CPU 1, a system memory 3 and an I / O buffer unit 4 connected to the CPU via a system bus 2, and an I / O bus. (5) a BCP (7) connected to the I / O buffer section, and an instruction memory section (8) and data connected to the BCP and connected to the I / O buffer section via an I / O bus (6). A memory interface 9, a latch 10 connected between the BCP 7 and the data memory 9, and a line interface connected to a TWNAX CABLE connected to the BCP and connected to a host computer. It comprises so that (11) is included. The system configured as described above is a system (or a personal computer having an emulation function with a host) used as a terminal of a host computer.

The software program of the present invention is stored and operated in the above system memory (3), the system bus (2), I / O buffer section (4), I / O bus (5), BCP (7), and line interface Part 11 is communicated with the host computer via the Tweenex cable.

FIG. 2 is a flow chart of the present invention, in which a screen color is selected on a configuration initial screen when operating a terminal system such that a desired color can be used regardless of a command of a host.

As a preferred embodiment of the present invention, the application of the present invention to an IBM (registered trademark) -based system 5250 terminal or a personal computer having an emulation function will be described in detail as follows.

If you mark an IBM attribute value as "IBM-att", that value has the value of OX20 IBM-att OX3F. In addition, analyzing the above attributes, OX07 is Normal, OX01 is Reverse, OX02 is Highlight, OX04 is Underline, OX08 is Blink, and the combination of these values is IBM attribute It represents.

Therefore, in the present invention, a new attribute table is created in the color selected by the user using these values so that the display can be displayed according to the user's preferences without being limited to the command of the host.

In general, a configuration initial screen by a configuration program allows selection of communication information, screen information, and printer information. First, screen information in the menu is selected (21). Then, it is determined whether the output screen is color or monochrome (22), and if it is monochrome, it immediately exits the mode of the present bar name, and if it is color, it is determined whether to change the screen property (23). So if you don't change the screen property, make sure that the screen property value or default value that you selected before is assigned (24), and if you change the screen property value, select the color that you want the screen property such as normal, underline, inverse, flicker, and highlight. (25). For example, the Normal attribute is the first color, the Inverse attribute is the second color, the Underline attribute is the third color, the Blink attribute is the fourth color, and the emphasis attribute is the normal emphasis. Since it is (Highlight), it can be designated as OX10.

Then determine if the IBM attribute value (IBM-att) is less than OX40 (i.e., less than OX3F) (26) and accept that value only if it is less than OX40 (27). Proceed to performance. Next, it is determined whether or not the adopted attribute value corresponds to the attribute designated by the user by changing the attribute as intended, and outputting it in the desired form. It is determined whether the attribute value (IBM-att) is a normal attribute (OX07) (28), and if it is correct, the screen is output in the pre-selected color (first color) (29). 30) If it is correct, the screen is processed to display in the pre-selected color (second color) (31), and if it is not corrected again, whether or not the adopted attribute value (IBM-att) is the emphasis attribute (OX02). If it is determined (32), the predetermined specific value (OX10) is set so that the normal state is outputted. It is judged whether or not it is underlined attribute (OX04) (34), and if it is corrected, it is processed to display in the pre-selected color (third color) (35), and if it is not corrected, the adopted attribute value is blinking again. OX08), and if it is correct (36), the process outputs the screen to the pre-selected color (fourth color) (37). After performing the above process, the next attribute is selected to be continuously searched for the attribute sent from the host (38), and the attribute value is converted to the initial value (OX00) (39). Sequentially retrieves the attribute value (IBM-att).

Therefore, the present invention carried out through the above process can change the screen properties irrespective of the command of the host, the user can freely change the screen properties according to their preferences to enhance the convenience in operating the terminal, It has the effect of designing a good program.
