Description

Detailed Description of the Invention (Technical Field of the Invention) The present invention provides an automatic terminal device that records the latest information communicated with a host computer in a bit serial format in a terminal device 1%, and displays the information as necessary. This invention relates to a terminal device with an added function for self-diagnosis.

(Prior art) Conventionally, information exchange with a host computer is in bit serial format, that is, JIS in accordance with R8, 2320.
A terminal device using the interface 1 of 06361 does not itself have a full monitor function for self-diagnosis. Even if the terminal device itself works perfectly,
When the terminal device is connected to the host computer, a situation may sometimes occur in which the terminal device does not work for some reason and the intended target sound cannot be achieved. If there is an error in the information from the host computer side or an information error from the terminal device side to the host computer side)
There are various causes such as failure of the device to operate properly.

(Problems with the prior art) In order for a user to find out whether the cause of a terminal device not working properly is on the host computer side or on the terminal device side, an expensive measurement instrument must be used. It is unrealistic to burden busy users with expensive measuring instruments, and terminal devices are shipped after thorough inspection, so it is difficult for users to determine whether the cause is on the host computer side or the terminal device side. had shortcomings that were not easily known.

(Object of the invention) The object of the present invention is to solve the above-mentioned disadvantages.
Of course, in addition to the original functions of the terminal device, it is also possible to exchange information with the host computer by using a memory cover for monitoring at the input/output terminal of the terminal device. A simple monitor function that records the history (contents of communication and the status of the terminal device at that time), reads out and displays the history as necessary, and allows you to easily identify the cause of the problem. The purpose is to provide a terminal device that can be used to explore social events.

Note that the terminal device includes a display device such as a 01'LT display device, but this display device is sent
! The character of the information is displayed simply without being too busy,
Furthermore, this is the main function of the display device, and it does not have the function of monitoring the cause of malfunction by itself. Therefore, there are other intended functions, and in addition to this, the present invention has an added function of reading out the history of information exchange with the host computer as described above and displaying it as necessary. It should be clearly distinguished from a display device that simply displays the characters of the information that has been transferred.

(Structure of the Invention) In order to achieve the above object, the terminal device of the present invention is a terminal device that communicates information in pinto serial format with a host computer. A memory for sequentially storing a predetermined number of hole information II--in the order in which it is transmitted from the host computer to the terminal device, a switch for reading out the information '4 stored in the memory, and a memory for reading out the information '4 stored in the memory based on the operation of the switch. A display N paths are provided for displaying the information 1 read from the host computer in the order of communication or in the reverse order, and the latest communication history between the host computer and the terminal device can be monitored at any time. Ru. The following terminal devices are used for tasks such as issuing slips for product sales, reservations, and estimates, inventory management, and automatic search systems, and are suitable for inputting multiple items such as product names and customer names frequently. Device (food selector) - example 1
The present invention will be explained.

(Example of the invention) FIG. 1 shows the configuration of an embodiment of a terminal device according to the present invention.

FIG. 2 is an explanatory diagram of one embodiment of the communication content holding format, and FIG. 3 is a format of one embodiment of the status structure.

FIG. 4 shows the configuration of an embodiment of the multi-item input device according to the present invention.
FIG. 5 is an external view of the multi-item input device according to the present invention, FIG. 6 is a flowchart, and FIG. 7 is an explanatory diagram of display contents displayed on the display.

In Fig. 1, 1 is a terminal device, there is an 0PU2 which controls the terminal device 1, and an external interface 3 and a P3s interface 4 which are connected to an external host computer using JIS O6361 bit 7 real based on information sound R82320. It is set up. The contents of communication between the terminal device 1 and the host computer, that is, information input from the host computer to the external interface 3, information output from the external interface 3 to the host computer, and status are successively stored in the memory 6 as history. The switch 7 is a switch that starts self-diagnosis, and every time the switch 7 is operated, it works to access the memory 611 via 0PU2', and the memory 6
The communication contents of the terminal device 1 stored in the terminal device 1 can be sequentially read out. Each time the display circuit 8 operates the switch 7t,
The read communication content information is displayed on the display 9.

In this way, the self-diagnosis circuit 5 including the memory 6, the switch 7, the display circuit 8, and the display 91 is added to the terminal device f1.

The memory 6 provided with the self-diagnosis circuit 51C exhibits maximum functionality with a small capacity.
Memorize the information of the information. In other words, during external transmission/reception processing, the contents (data) and state (status) of the communication, as well as the latest required number of characters for the meeting, for example, 10 characters, are always updated and retained in the memory 6 (when the communication is performed). (If not, only the current status is retained).

If my friend and I connect terminal device 1 to the host computer and it does not work properly, we recommend using the latest 10
This is based on the expectation that if there are enough characters, the cause can be clarified. Therefore, the number of characters is not necessarily limited to 10 characters, but for convenience of explanation, the number of characters will be explained below as 10 characters.

The capacity of the memory 6 is approximately 20 bytes. The contents stored in the memory 6 are displayed on the display 9 at any time by operating the self-diagnosis switch 7, but when the switch 7 is shifted from the self-diagnosis mode to the online mode,
The external control PAυ apparently clears all the contents of the memory 6.

FIG. 2 is a diagram illustrating an example of a communication content holding format. For example, when there is no communication with the host computer, the status at that time is stored in the addresser 1 of the memory 6. In the diagram, SP is the start point, NP is the latest store point lt
In this case, when the self-diagnosis switch 77 is activated, the 1st character (OHARAOTER, 2nd
(abbreviated as OH in the figure) indicates that only the eye status is displayed. For example, when communication for 6 characters is performed, address number 1 of memory 6 stores the status of the first character, address +2 stores the data of the first character, and so on. has the status of the 6th character, Addressna 1
In 2iC, the data of the 6th character is stored and held. In this case, when the self-diagnosis switch 7 is activated, the information stored in the memo U61C is read out.
The status of the first character held at the address φIK in the memory 6 and then the data of the first character held in the address bar 2 are sequentially displayed on the display 9 every time seven switches are operated. Similarly, the status and data of each character are sequentially displayed, and the status and data of the sixth character are displayed. The status and data of the sixth character is the latest information.

The range indicated by the thick line between 8P and NP is the displayable range k
I'm doing it. In addition, in the explanation of the display above, it was explained that the status and data are displayed sequentially, but the display 9
It goes without saying that if the number of display digits is increased, the status and data of each character can be displayed at the same time. Even when communication for 10 characters is performed, communication for the above-mentioned 6 characters is performed, which is the same as in the fc case. Next, when communication for 13 characters is carried out and the fc is captured, the status and data of the 1st to 3rd characters that were previously stored and retained will be changed to the status and data of the 11th to 13th characters that have been newly updated. and rewritten to data. That is, the contents previously stored in the status and data of the 11th character to the 13th channel are updated. Therefore, in this case, when the self-diagnosis switch 7 is activated, the address information 7 of the memory 6 will be displayed on the display 9. From the stator and data of the 4th character held in the addresser 5. The latest status and data of the 13th character held in the screen 6 are displayed.

FIG. 3 shows the format of a simple example of the status structure, and the status is also made up of 1 number, 9 bytes and 8 bits, like the data. B÷0 bit [IfiO
TS (Ready to Transmit) signal, RT8 (Request to Transmit) signal for B1 bit, DSR (Data Set Ready) signal for B2 bit, and DTFL (Data Terminal Ready) signal tone for B3 bit. When each signal is on, it is logic "1" (hereinafter simply abbreviated as rg, ro). B 4 bits are “1” when terminal device 1 is receiving;
When transmitting, “0” is set, and the corresponding B4-4 bit v
Transmission and reception can be determined by looking at the information. Bsu5#-
i nozoretail error, B6 is off 2nd e, i'-*
B*7 represents a framing error, and is set to "1" when there is an error during reception. If there is an error during transmission, the key is set to 0.

FIG. 4 shows the entire configuration of another embodiment, and FIG. 5 is an external view of the terminal device shown in FIG. 4.

4 and 5, the following example is shown in which the terminal device includes a multi-item input device 31't.

This multi-item input device 31 is used to input a desired item from among a plurality of item sheets (not shown) stored in a winding frame at the bottom of a plurality of keysades 16 arranged in a matrix for inputting items. Select with the selection key 17, separate and feed out the item sheet, and input the item information by operating the item formula keys at positions corresponding to the positions of the many items written on the item sheet. This is how it was done.

Displays 11, 12 and 13 and switches 14 and 15 are provided inside the main body of the multi-item input device 31 and below the numeric keypad cover 10.

The display 1i, 12.13 is the display 9' explained in FIG.
The 4t% friend switches 14 and 15 are explained in FIG. 1, and the next switches 7t are each further explained.

The display 11 shows the order display money, and the displays 12 and 13 display the contents held in the memory 6.

The switch 14 is a mode switch for switching to the self-diagnosis mode, and when the switch 14 is activated, the self-diagnosis is started. The switch 15 is a switch that sequentially reads out the status and data of each character held in the memory 6Vc, and the display contents of the status and data displayed on the display 1912.13 are sequentially changed by operating the switch 15.

Note that 16 is the item type key, 117 is the page selection key, and 18
19 represents a shift key, 19 represents a numeric keypad, and 20 represents an external connection key.

Next, the present invention will be explained in detail using the 70-chart in FIG. 6 and the display content explanatory diagram displayed on the display device in FIG. 7.

The terminal device 1 performs data processing while exchanging information with the host computer. At this time, the data input to the external interface 3 and the status of the terminal device 1 at that time are stored in the memory 6, and at the same time, the data output from the external interface 3 and the status of the terminal device l at that time are stored for 10 characters as described above. are stored sequentially (step 50.51). The nine switch 14 provided in the terminal device 1 connected to the host computer is operated to set the self-diagnosis mode (step 51).

The display 11 displays "o" indicating the order, and 0PU2 is the memory 6? ! - The status of the first character of the 10 characters of status and data immediately before accessing and entering self-diagnosis is read from the memory 6, and the next status after being read is displayed 1Fp12.1
3 (steps 52 and 53). Then, when switch 15t is activated (step 54.55), 0P
U2 accesses the memory 6, reads data t'' of the first character from the memory 6 (step 52), and displays the contents on the display 12, 13. At this time, the display 11
displays rQ,,1. The number rOJ on the display 11,
rlJ.

A dot is added to the bottom right of ``...'' to distinguish between status and data. Next, when the first switch is operated in sequence, the same process as before is performed, and the display 12.13 displays the contents and order of the status and data for the immediately preceding 10 characters (steps 55, 52, and 53). ). In this manner, each time the switch 15t is actuated, the IC status and the current status are sequentially displayed on the display 12.13 as shown in FIG. 7, and 10 characters are displayed endlessly. This allows the user to view the display 12.
From the contents of the data displayed in 13 and the status at that time, the system including the terminal device 1 and the host computer (
system) is working correctly and you can find out the cause.
It is easy to determine whether there is an error in the information from the host computer or whether the terminal device 1@I/C914 exists. If there is an error in the information on the host computer side, the terminal device will be able to operate normally by changing the program to the correct one. That is, by disabling the self-diagnosis 11 when correct information appears to be transferred from the computer side.

Returning to the online mode, the terminal device 11 performs data processing correctly (steps 54, 563. At this time, all contents of the memory 6 are cleared as described above).

Although the explanation has been given using a terminal device that is a multi-item input device as an example, the present invention is applicable to all other terminal devices. It goes without saying that a display method that can display the Ia12.13 meeting status and the event status at the same time may also be adopted. Also, the display order may start from the most recent information input to the memory.

(Effects of the Invention) As explained above, according to the present invention, communication information input and output from the input/output part of the terminal device, that is, from the input/output processing routine, is stored in the history memory, and as needed. The communication information rice B! Since the information is read out and displayed, it is useful for analyzing complaints about insect repellent when the host computer and terminal device are connected for the first time, and service-related operations are made extremely easy. Further, since various information at the time of a complaint is displayed, the cause of the complaint can be quickly investigated and the terminal device can be brought back to normal operating sound quickly.
