Description

[Detailed Description of the Invention] [Summary] When processing data of a multi-mode terminal device is not suitable for processing by another terminal device as it is,
The system host changes the processing mode of the multimode terminal device to suit data processing at another terminal device, and the changed data is transferred to the other terminal device via the system host for processing. Also, thereafter, the multimode terminal device is returned to its original processing mode.

[Industrial application field]

The present invention relates to a multi-mode processing method in which a host recognizes the operating mode of a station and processes the operating mode in a system configured with a mixture of stations that can operate in various operating modes.

An information processing system has a single,
Alternatively, some stations have a configuration in which multiple stations are connected. The stations in early systems of this type had a single operating mode, but as more high-performance stations have been developed in recent years, stations with multiple operating modes have appeared. There is a need for the host side to recognize the operating mode and proceed with the required processing.

When such stations are connected to a host to perform the required processing, the host that controls the stations must recognize its operating mode, but this recognition must be done through both software and hardware. It is required that it can be easily performed without being influenced by the connected station,
This has been highlighted as a technical issue that needs to be solved.

[Conventional technology]

As a method for the host to understand the operation mode of the station as described above, as shown in FIGS. 6 and 7, when the host 1 attempts to send data to station A (step S1 in FIG. 7),
Perform a data check (steps in Figure 7)
S2), store all the operation mode information for station A in the operation mode information storage area 2 of host 1 (step S3 in Figure 7), and learn how to use it when necessary, When a new operating station B is added (see Figure 8), a special command is prepared for that purpose.
If the operating mode (state) of the station is required (step S10 in Figure 9), the host 1 sends a special command to the station (step S11 in Figure 9), and the station side executes the command. It processes and sends the operation mode information data back to the host 1. For station A that is not supported by that command, an error termination is detected (Y in step S12 in Figure 9), and the station A is assumed to be in the basic operation mode, and the information indicating that is the operation mode of host 1. Although the command is stored in the information storage area 2, no error is detected for station B supported by the command (N in step S12 in FIG. 9).
There is a method in which the operation mode information data sent back from station B is stored in the operation mode information storage area 2 of the host 1 and made available for use.

[Problem that the invention seeks to solve]

The former method has the disadvantage that it increases the processing load on the host 1 because it becomes necessary to check all the data stored in the operation mode information storage area 2 of the host 1. This method will result in an error on unsupported stations, and the host side must also create a special sequence for checking the operating mode, which increases the processing load.

The present invention was created in view of the above-mentioned problems, and its purpose is to provide a multi-mode processing method that can easily recognize and process multi-modes while reducing the burden on the host. do.

[Means for Solving the Problems] FIG. 1 shows a block diagram of the principle of the present invention. In this figure, a system host 10 includes a station 11 to which terminal devices operating in multi-mode and other terminal devices can be connected. The host 10 of the system configured as described above saves 12 the mode information (status information) of the multi-mode terminal device in the station 11, sets 13 new mode information for the multi-mode terminal device, and It is configured to use commands to read processing information 14 from the multi-mode terminal device, transfer processing information 15 to other terminal devices, and reset 16 saved mode information to the multi-mode terminal device.

[Effect]

If the system host 10 wishes to operate the multimode terminal in a different mode of operation than the mode of operation carried out on the multimode terminal of the station 11, it first uses a command to The mode information for the current operation mode is saved in the system host 10, and the mode information for the new operation mode is set in the multimode device using a command.

In this way, the processing information obtained from the multimode device is transferred to another terminal device using a command to perform the processing, and the saved mode information is set in the multimode terminal device in advance. Restore operating mode.

Because of this kind of processing, it is unnecessary for the host to check all data, etc., and there is no need to create a special sequence for mode checking in the host. In this way, the burden on the host can be reduced. Moreover, mode recognition for this purpose becomes simple.

〔Example〕

FIGS. 2 and 3 show an embodiment of the present invention.
When the host 20 receives an instruction 21 to “read and print the screen of station A,” the mode information (status information) of station A is sent to the Read Buffer.
The host information is saved in the host information save area 23 of the host 20 using the command 22 (24). At that time, the memory contents and transfer format of station A are as follows.
Indicated by reference numbers 25 and 26. Assume that the status information (response mode) of the transfer format is, for example, alphanumeric mode, and the data is JEF code BOA5 ("love" on the screen). If this data is directly transferred to the printing device 61 via the host 60 and printed as shown in FIG. 5, it will be printed as a blank and the katakana "mi" as shown.

However, according to the present invention, such inconvenience can be avoided because processing is performed as follows.

That is, first, after the above-mentioned evacuation processing is performed, the write command 27 is used to move the station A.
The state information in the memory contents 25 of is set to the alphanumeric + kanji response mode 28, 29.

After that, the host 20 uses the Read Buffer command 30 to read data 31 from the memory contents 25 of the station A. The transfer format at that time is 32, and in the above example, "28" is added before "BOA5" to indicate that it is a Kanji order.

In this way, the data read into the host 20 is transferred to the printing device of station A using the write command 33 and printed 34. The transfer format at that time is 35, and the data
An order “28” is added in front of BOA5, which says “handle the data as kanji”. Therefore, the hard copy of the data BOA5 is shown in Figure 3.
The desired kanji ``love'', such as 6, will be printed.

After this printing is completed, the original state information 38 saved in the host information save area 23 of the host 20 is written to the state information area 39 of the memory contents 25 of the station A using the write command 37.

FIG. 4 briefly shows a series of these operations.

In the above embodiment, a printing device is used as an example of another terminal device of the station 11, but other terminal devices such as other multi-mode terminal devices may be used.

〔Effect of the invention〕

As explained above, according to the present invention, there is no need to check all data etc. in the system host as in the prior art, and there is no need to prepare a special sequence for mode checking. Therefore, the burden on the system host is reduced and mode recognition becomes easy.
