JPH077966B2 - Data input method - Google Patents

Description

The present invention relates to a data input method, and more particularly to a data input method using a remote typewriter.

[Conventional technology]

In the conventional data input method of this type, at the time of data input, the input code is printed by the remote typewriter itself, and the input code is sent to the remote typewriter control device.
When the remote typewriter control device receives an input code from the remote typewriter, it transfers the received code as it is to the central control device.

[Problems to be solved by the invention]

The above-mentioned conventional method has a drawback in that the remote typewriter operator cannot know whether the input code from the remote typewriter has reached the remote typewriter control device correctly.

It is an object of the present invention to, when data is input from a remote typewriter, a remote typewriter control device by returning an input code from the remote typewriter to the remote typewriter for printing so that the remote typewriter and the remote typewriter control device. It is about trying to guarantee data transfer between.

[Means for solving problems]

The system of the present invention is a data input system by a remote typewriter, and when the remote typewriter control device receives an input code from the remote typewriter, the input code is stored in a memory and returned to the remote typewriter, Further, when the input code indicates the end of data input, all the input codes stored in the memory are sent to the central processing unit, and the remote typewriter does not print this input code when inputting the input code. It is characterized in that the input code returned from the writer control device is printed.

〔Example〕

 Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, which includes a central processing unit 10, a channel unit 20, a remote typewriter control unit 30, two modems 40 and 50, and a remote typewriter 60.
Consists of.

In FIG. 1, the central processing unit 10 is connected to a channel interface section 31 of a remote typewriter control unit 30 via a channel unit 20. The channel interface unit 31 is connected to the control device 32 that controls the exchange of data between the central processing unit 10 and the remote typewriter 60.

A memory unit is connected to the control device 32, and controls and stores the microprogram and data. The control unit 32 is connected to the remote typewriter 60 via the input / output interface unit 34 and the modems 40 and 50 to exchange data.

Next, the operation of this embodiment will be described with reference to FIG.

In the remote typewriter 60, when inputting data from the keyboard, the remote typewriter 60 itself does not print the input code, but only sends the input code to the remote typewriter control device 30. When a data code is received from the remote typewriter controller 30, the received code is set to be printed.

Now, when the code "A" is entered from the keyboard of the remote typewriter 60, the code "A" is sent to the remote typewriter control device 30. When the remote typewriter control device 30 receives the code "A", the code "A" is stored in the memory unit 33.
The code "A" stored in the memory unit 33 and returned to the remote typewriter 60. The remote typewriter 60 prints the code "A" returned from the remote typewriter control device 30.

Next, when the code "B" is entered from the keyboard of the remote typewriter 60, the code "B" is sent to the remote typewriter control device 30. Upon receiving the code "B", the remote typewriter control device 30 stores the received code "B" in the memory unit 33 and returns the code "B" stored in the memory unit 33 to the remote typewriter 60. The remote typewriter 60 prints the code "B" returned from the remote typewriter control device 30.

In this way, data is sequentially exchanged between the remote typewriter 60 and the remote typewriter control device 30. Then, a specific code indicating the end of data transfer, such as "〆", is decided in advance, and when the code "〆" is entered from the keyboard of the remote typewriter 60 at the end of input, the code "〆" is controlled by the remote typewriter. Device 30
Sent to.

When the remote typewriter control device 30 receives the code "〆", it stores the received code "〆" in the memory unit 33,
Next, the code "〆" stored in the memory unit 33 is returned to the remote typewriter 60, and it is judged that the data transfer is completed by the code "〆", and all the transfer data "AB ... .. is transferred to the central processing unit 10.

〔The invention's effect〕

As described above, according to the present invention, in the remote typewriter control device, the reception code from the remote typewriter is returned to the remote typewriter and printed.
There is an effect that the operator of the remote typewriter can confirm the normality of data transfer between the remote typewriter and the remote typewriter control device.

Claims (1)

[Claims] 1. A data input method using a remote typewriter, wherein when a remote typewriter control device receives an input code from the remote typewriter, the remote typewriter controller stores the input code in a memory and returns it to the remote typewriter. When the input code indicates the end of data input, all the input codes stored in the memory are sent to the central processing unit, and the remote typewriter does not print the input code when inputting the input code. A data input method characterized in that an input code returned from the remote typewriter control device is printed.
