Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a text information display method for a terminal device that receives text information continuously transmitted from a host computer and displays it on a display device.

[Conventional technology]

Conventionally, there have been two display methods when receiving text information continuously transmitted from a host computer and displaying it on a display device of a terminal device.

(1) The text information for each screen of the display device is displayed sequentially according to the screen number specified by the host computer, and the screen is moved by pressing the screen turn key provided on the terminal device (for example, Kaisho 62-2
(See Publication No. 85126).

(2) Press the screen stop key provided on the terminal device,
Stops continuously displayed text information (in this case, the text information after stopping is not displayed)
.

[Problem to be solved by the invention]

However, the above display method (1) cannot be executed unless the host computer's operating system (O8) has the function of specifying a screen number and displaying text information for each screen on the terminal device. The problem was that I couldn't do it.

In addition, in display method (2), the text information sent from the host computer is displayed at high speed on the display device of the terminal device, so when the desired text information is displayed, press the screen stop key. There is a problem in that it is very difficult to stop the display of text information, and furthermore, it is not possible to continue displaying the text information after it has been stopped by pressing the screen stop key.

This invention has been made in view of the above points, and is capable of continuously displaying text information continuously transmitted from a host computer on a display device of a terminal device, and stopping one screen from an arbitrary point in time. It can be displayed in the stopped state, and when it is released, the text information that follows that screen is displayed continuously again, and when it is displayed in the stopped state, the text information for the previous screen is also in the stopped state. The purpose is to make it possible to display.

[Means to solve the problem]

In order to achieve the above object, the present invention temporarily displays received text information in a text information display method of a terminal device that receives text information continuously transmitted from a host computer and displays it on a display device. A display buffer memory for sequential storage and display, a next screen display key, and a screen stop release key are provided, and normally the received text information is sequentially and continuously displayed on the display device, and the next screen display key is pressed. Then, after receiving one screen worth of text information, it stops sending the text information to the host computer, displays the received one screen worth of text information on the display device in a stopped state, and releases the screen from stopping. When the key is pressed, the display on one display device is returned to the normal state and transmission of text information to the host computer is resumed.

Furthermore, a previous screen display key is provided, so that if the previous screen display key is pressed while the display device is displaying one screen worth of text information in a stopped state, the previous screen display key will be displayed. It is preferable that the text information is displayed on the display device in a stopped state.

[For production]

In the text information display method of the terminal device according to this invention,
If the next screen display key is pressed while text information received from the host computer is being displayed continuously,
One screen worth of text information received from that point on is displayed in a stopped state, and the normal display state is returned to when the screen stop release key is pressed.

Furthermore, if the previous screen display key is pressed while one screen's worth of text information is displayed in a stopped state, it is possible to display the previous screen's worth of text information. In addition to being visible when stopped,
You can also view the previous screen's worth of text information even when the screen is stopped.
