Abstract

PURPOSE:To simplify the operation of a data terminal equipment by storing the connection data received from a host device in a rewritable nonvolatile memory and decoding and executing the connection data. CONSTITUTION:A terminal equipment 1 contains a procedure reserving part 14, i.e., a rewritable nonvolatile memory consisting of a RAM and backed up by a battery, etc. While a host computer 2 contains a procedure file 21 which stores the connection procedure data showing the contents of the connection procedure. When the equipment 1 is installled, an operator supplies a prescribed command through an input part 11 of the equipment 1 and receives the connection procedure data stored in the file 21 through a communication control part 13 of the equipment 1 after a connection request is decided by the computer 2. Thus said procedure data is stored in the part 14 via a procedure executing part 15 and the necessary processing is carried out.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data terminal device used in a database or the like.

[Conventional technology]

Conventionally, in order to use a database, after connecting a terminal device to a host computer, a connection operation was required to send and receive various commands, including D codes and passwords, between the terminal device and the host computer. These operations are performed according to the instructions in the manual.

[Problem that the invention seeks to solve]

However, even though the connection operation is instructed in the manual, if the host computer is different, it is necessary to arrange it to suit the difference, but this arrangement requires interrogation knowledge, so it is necessary to have appropriate training. Only the operator can perform these operations, and it is extremely troublesome to perform these operations each time a connection is made.

Means for Solving Problem C] In order to solve these drawbacks, the present invention provides a rewritable nonvolatile memory for storing connection procedure data sent from a host device, and a rewritable nonvolatile memory for storing connection procedure data sent from a host device, The terminal device is provided with an execution means for decoding and executing the data.

[Effect]

Connection processing between the host device and the terminal device is performed without the intervention of an operator.

〔Example〕

FIG. 1 is a block diagram showing one embodiment of the present invention.

In the figure, a 1-digit terminal device, 2Ff, a host device, a terminal device 1#i display section 10, an input section 11 such as a keyboard, a central control section 12 that controls the movement of the entire terminal device,
A communication control unit 13 including an R8232C interface etc. supplies connection procedure data supplied from the host device 2 via the communication control unit 13 to a procedure storage unit, decodes the data, and follows the connection procedure data. a procedure execution unit 15 that executes the procedure, and a procedure storage unit that is a rewritable non-volatile memory composed of, for example, battery-backed RAM to store connection procedure data supplied via the procedure execution unit 15; It consists of 14.

The host device 2 is composed of a host computer 20 and a procedure file 21 in which connection procedure data representing the contents of a connection procedure to be executed at the time of connection in the terminal device 1 in order to utilize the database is stored. As shown in FIG. 2, the format of the data stored in the procedure file 21 is composed of an identifier for identifying that it is different from general data in the communication control unit 13, and connection procedure data. The procedure data consists of a command section consisting of various instructions such as an instruction to send data, an instruction to wait for data reception, and an instruction to check whether communication is possible with the terminal device, and a data section. It is configured.

FIG. 3 is a flowchart showing the operation of the device shown in FIG. 1, in which the data for connection is extracted from the host device at the time of installation and stored, and the next time the connection operation is performed according to that data. It shows.

In FIG. 3, during installation, step 100 is "yr:
Since it is determined that the connection is sJ, the connection operation shown in step 101 is started. Note that whether or not it is time for installation is determined based on, for example, whether data is written in the procedure storage section 14 or not.

The operation in step 101 is performed by the operator inputting a predetermined command into the input unit 11, but this command is a fixed command and is written in the manual regardless of the type of host device and the content of the data to be used. All you have to do is perform the operations as shown in the table below, and there is no need to arrange commands depending on the type of data to be used, unlike in the past, so even those without special interrogation knowledge can easily perform the operations.

The command sent by performing the operation in step 101 is transmitted to the host device 2, where it is determined whether or not it is a connection request for connecting to the procedure file 21, as shown in step 102. This step 10
2 is determined to be YESJ, the host device 2 sends the connection procedure data stored in the procedure file 21 to the terminal device 1 as shown in step 103, so that the data is transferred to the terminal device 1 as shown in step 104. It is received by device 1.

When the communication control unit 13 of the terminal device 1 that received this data detects that the received data includes the identifier shown in FIG.
-yasJ, the connection data sent from the host device 2 side is stored in the procedure storage unit 14 via the procedure execution unit 15. After that, the terminal device 1 performs step 10
As shown in 7, normal processing, in this case general processing required during installation, is performed to complete the installation procedure. At this time, even if the power is turned off, since the procedure storage unit 14 is a non-volatile memory, the connection procedure data once written remains without being lost even after the power is turned off.

Next, when the power is turned on to the terminal device, a determination is made in step 10G, but since this is not the time for installation, this step is determined to be "NO", and the "
The process of ``connection procedure data decoding process'' is performed. This process is performed as follows. When the power is turned on, the data stored in the procedure storage unit 14 is read out to the procedure execution unit 15, and when executed, the process to be executed and the corresponding process are displayed on the screen of the display unit 10, as shown in FIG. The symbol for the key on the keyboard is shown. Therefore, when the operator looks at the screen and presses the keyboard corresponding to the process he wants to perform, the first stage data for connection is sent to the host device 2, and the host device 2 that receives this data is connected to the terminal device. The terminal device is requested to send a unique identification symbol, and this is displayed on the screen of the display unit 10.

Here, when the operator sends a predetermined identification symbol to his own terminal device, the host device 2 that receives this identification symbol next requests the terminal device 1 for a password, so the operator inputs the password. However, when this is decoded by the host device 2, the necessary message is sent from the host device 2 to the terminal device 1, and the purpose is achieved.

In order to relocate this device to a different system, it is only necessary to reset the data in the procedure storage section 14 before installing it.

〔Effect of the invention〕

As explained above, in the present invention, the terminal device is equipped with a rewritable memory that stores data necessary for performing the connection procedure, and the connection process is executed using the data stored in this memory. is a special specialty wholesaler
This has the effect of allowing you to operate the equipment at your fingertips.
