Abstract

PURPOSE:To unnecessitate the various kinds of setting on the sides of a main body and a terminal by judging the change of a line state from the main body side of a computer corresponding to a line state signal and automatically performing the various kinds of setting. CONSTITUTION:At a main body 2 of a computer, the state of a line to be used is written in a line managing table 23. On this stage, an irreducibly minimum information (such as line speed or synchronizing system) for communication between the computer and the terminal is written. Then, a line information conversion part 22 always refers to the line managing table 23 and analyzes the contents, and the contents are converted as corresponding simplified signals decided in advance and transmitted to a line state signal transmission part 21. This signal is transmitted from the line state signal transmission part 21 through a signal line 3 to a line state recognition part 15 on the side of a terminal equipment 1 and recorded on a state setting memory 1 6 by the line state recognition part 15 as, the set information (data) of the own terminal. This operation occurs by linking the main body 2 of the computer and the terminal equipment 1 and does not depend on the ON/OFF of a power source at the terminal equipment 1, especially.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal device, and more particularly to an automatic setting system for a terminal device connected to a computer via a communication line.

[0002]

2. Description of the Related Art Conventionally, various settings relating to a terminal device have been made at two places, that is, the main body side and the terminal side. The main body side manages the line speed and the type of terminal to be connected for each line (port), and controls the input / output of data to / from the line based on this management information. On the other hand, on the terminal side, the internal operation status setting function allows the user to input the information necessary for operation such as the speed of the line to which the terminal is connected, the type of synchronization, etc. and save these inside. At the time of actual operation, it was operating in the setting state according to the specified information. All of these settings on the main body side and the terminal side were artificially made, and even though the results of both settings affect each other, they were made separately and independently on each side.

[0003]

In this conventional method for setting a terminal including a line performed on the computer main body side and the terminal side, since both settings are independent of each other, the change in one setting is known to the other. It was never done. So, for example,
When a terminal connected to a line with a computer and operating is connected to another line (which has a different status) (this can be regarded as a change in the line status from the terminal). For example, the terminal does not work because it tries to communicate with the main body side in the previous setting state, and in order to operate this, the user needs to know various information for setting, and the main body side and the terminal side There was a problem that the terminal setting had to be performed every time the terminal was connected, unless the line status did not change.

An object of the present invention is to exchange line (terminal) setting information, which has been separately managed on the computer main body side and the terminal side, with each other, thereby automatically setting the operation of the terminal according to the change of the line state. It is to provide an automatic setting method for the device.

[0005]

According to the automatic setting method of a terminal device of the present invention, in a terminal device connected to a computer main body through a communication line (port), a line status signal transmitted from the computer main body. It is equipped with a line status recognition unit that recognizes the status and a status storage unit that stores the recognition result and various terminal setting information entered by the user, and judges the change of the line status from the computer main unit side by the line status signal. Then, various settings required for operation are automatically performed.

[0006]

The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an embodiment of the present invention. The computer main body 2 and the terminal device 1 are provided with a signal line 3 and a data line 4
Through the connector 5. Inside the computer main body 2, a signal transmission unit 21 for transmitting an information signal regarding the line state to the signal line 3 at the end point of the signal line 3.
There is a line management table 23 that manages all the line information held by the computer, is converted into a line status signal, and vice versa is sent from the terminal 1 side to this signal sending unit 21. An information conversion unit 22 for converting the terminal information into the format of the line management table 23 is connected. Inside the terminal device 1, there is a line state recognition unit 15 at the end of the signal line 3, and a state setting memory 16 for storing the setting state of the terminal device 1 ahead of this.
The keyboard 6 is connected to the keyboard 11 through the keyboard interface 12.

In the present invention, first, the computer main body 2 sets the state of the line to be used by writing it in the line management table 23. At this stage, it is assumed that the minimum information (line speed, synchronization method, etc.) for communication between the computer and the terminal is written in the line management table 23. The line information conversion unit 22 always refers to the line management table 23, analyzes the content of the line management table 23, converts the contents into a simple signal corresponding to a predetermined value, and transmits the converted simple signal to the line status signal transmission unit 21.
The line status signal sending unit 21 sends this through the signal line 3 to the line status recognition unit 15 on the terminal device 1 side, and the line status recognition unit 15 records it on the status setting memory 16 as setting information (data) of the own terminal. .. This operation occurs due to the connection between the computer main unit 2 and the terminal device 1, and does not particularly depend on ON / OFF of the power supply of the terminal device 1.

Next, on the side of the terminal device 1, the information (terminal type, mode, etc.) peculiar to the terminal is input through the keyboard 11 and the keyboard interface 12, and the contents are similarly recorded in the state setting memory 16. When the power of the terminal device 1 is turned on, the terminal device 2 displays the state setting memory 1
Initial setting is performed according to the contents of 6. At this time, the power ON is notified to the computer main body 2 through the signal line 3, and in the computer main body 2, the interrupt controller 25 makes a terminal connection by interrupt processing. After the power is turned on, the terminal device 1 sends out the contents of the state setting memory 16 to be notified to the computer main body 2 to the computer main body 2 through the input / output interface 18 and the data line 4. The computer main body 2 saves the data in the main storage device 24 and then saves it by converting it into the format of its own line management table 23 via the line information conversion unit 22.

By the above operation, both the computer main body 2 and the terminal device 1 mutually convert their own unique information, so that the terminal device 1 is automatically appropriate even when it is connected to another line. Settings will be made. After setting the terminal device 1, the keyboard 11 and the keyboard interface 1
2 and the communication memory 17, the display 13, and the display interface 14, a normal state in which data exchange with the computer main body 2 is performed.

[0010]

As described above, according to the present invention, since the computer and the terminal exchange information with each other, the internal setting suitable for the state of the line to which the terminal is connected is automatically performed. There is an effect that various setting processes performed on the main body side and the terminal side are unnecessary when the connection is made.
