Abstract

PURPOSE:To log on correctly and automatically even when the same starting character string is contained in a received character string plural times by adding a timer part and a comparative value storage part which is stored with a clocking comparative value newly to an automatic log-on function. CONSTITUTION:A discrimination part 3 outputs a coincidence signal to a control part 8 when an input from a reception part 4 coincides with the starting character string of a starting character string storage part 1. Consequently, the control part 8 while initializing the timer part 6 instructs the start of clocking and also compares the clocked value of the timer part 6 with a clocking comparative value set previously in the comparing and storage part 7. The control part 8 initializes the timer part 6 every time an output is detected during reception. Consequently, transmission is placed in a wait state as long as the clocked timer of the timer part 6 does no reach the comparative value and reception is carried on. When the transmission from a host stops, the clocked value of the timer part 6 is updated one after another and when the value reaches the comparative value in the storage part 7, the control part 8 transmits a character string for answering corresponding to the received starting character string.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a communication terminal device having a function (referred to as automatic logon) of executing a transmission/reception procedure according to a stored character string.

2. Description of the Related Art Conventionally, there have been communication terminal devices (referred to as data terminals) that connect to a communication line and transmit and receive data, and perform automatic logon according to a pre-stored character string.

Hereinafter, the conventional communication terminal device as described above will be explained with reference to the drawings.

FIG. 2 shows a block diagram of a conventional communication terminal device. In FIG. 2, reference numeral 11 denotes an activation character string storage unit that stores an activation character string, 12 a response character string storage unit that stores a response character string, and 13 that stores a match between the activation character string and the received character string. A determining unit for comparison, 14 a receiving unit for receiving character strings, 1
5 is a transmitter that transmits the character string stored in the response character string storage section 12; and 16 is a controller that operates the transmitter 15 based on the matching output of the discriminator 13.

Regarding the conventional communication terminal device configured as described above,
The operation will be explained below.

It is now assumed that this communication terminal device is connected to a host device via a communication line.

First, characters sent from the host device via a communication line are received by the receiving section 14 and outputted to the discriminating section 13 as a character string.

The determining unit 13 compares the output from the receiving unit 14 with the activation character string previously set in the activation character string storage unit 11 by the user, and outputs a matching signal to the control unit 16 if they match.

The control unit 16 uses this matching signal to generate a response character string, ia
In order to transmit the character string stored in the storage unit 12 (response character string corresponding to the activation character string), the transmitting unit 15 is activated and the character string is transmitted to the host device.

Repeat these steps to perform automatic logon.

Further, the above-mentioned operation will be explained using a specific example.

Suppose that the activation character strings stored in the activation character string storage unit 11 are 'ABC' and 'DEF', and the response character strings corresponding to these respective activation character strings are '***' and 'MO++'. , the receiving unit 14 (the character string received by the iron is ' 0123
456789, A, B CJ, the determination unit 13 determines the received character string '0123456789AB
The character string rABcJ included in CJ and the activation character string 'ABC' stored in the activation character string storage unit 11
Assuming that the number 7 matches, the match signal is output to the control section 16.

The control unit 16 uses the input coincidence signal to transmit the transmission unit 15.
and sends a response character string r*** corresponding to the activation character string rABcJ to the host device. Automatic logon is executed by performing the above steps multiple times.

Problems to be Solved by the Invention However, in the above configuration, if the same activation character string is heard multiple times in the received character string (for example, in the above specific example, if the received character string is "ABCO1234567")
89ABC, this means that this received character string contains two activation character strings rABcJ), and upon receiving the first activation character string rABcJ, the communication terminal device ``column r***'' is sent to the host device. That is, following the startup character string rABcJ from the host device, "0123456
When 789ABCJ is sent, the response character string r
Since ***J is sent, the host device cannot receive this response character string and has a problem in that automatic logon cannot be achieved.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a communication terminal device that can correctly perform automatic logon even when the same character string appears multiple times in a received character string. It is something to do.

Means for Solving the Problems In order to solve the above problems, the communication terminal device of the present invention includes an activation string storage section that stores an activation string, and a response string storage section that stores a response string. , a receiving unit that receives a character string, a determining unit that compares the activation character string with the received character string, a transmitting unit that transmits the character string stored in the response character string storage unit, and a timer; A comparison value storage section for storing time comparison values and a matching output from the discrimination section instruct the time measurement section to start time measurement, and a reception detection output from the reception section initializes the time measurement section. It is comprised of a control section that determines whether there is a match with the comparison value storage section, and if there is a match, extracts a response character string from the response string storage section and sends it to the transmission section.

Effect With this configuration, even if the same character string is included in the received character string, the timer is initialized by the reception detection output of the receiver, so as long as the reception continues, the transmission will be in standby mode and the reception will continue. Since the response character string is sent to the host device when it is determined that the process has been completed, automatic logon can be executed correctly.

EXAMPLE An example of the present invention will be described below with reference to the drawings.

FIG. 1 shows a block diagram of a communication terminal device in an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes an activation string storage section 1f in which an activation string is written, 2 a response string storage section that stores a response string, and 3 stored in the activation string storage section 11. 4 is a receiving unit that receives the character string; 5 is a transmitting unit that transmits the character string stored in the response character string storage unit 2; 6 is a timer. 7 is a comparison value storage unit that stores a time comparison value; 8 is a comparison value storage unit that stores a time comparison value; and 8 is a comparison value storage unit that stores a time measurement comparison value; At the same time as instructing the receiving section 6 to start timing, the receiving section 4
Initializes the clock unit 6 based on the received detection output, and also determines whether the measured value matches the comparison value storage unit 7, and if they match, extracts a response character string from the response character string storage unit 2 and transmits it. This is a control section that sends data to section 5.

The operation of the communication terminal device configured as described above will be explained below.

It is assumed that the combined communication terminal device is connected to the host device via a communication line as in the conventional example.

First, the characters sent from the host device through the communication line are received by the receiving section 4 and input manually as a character string to the discriminating section 3. The determining unit 3 compares the input from the receiving unit 4 with the activation character string previously set in the activation character string storage unit 1 by the user, and outputs a matching signal to the control unit 8 if they match. The control unit 8 initializes the timekeeping unit 6 based on this coincidence signal, and at the same time instructs the start of timekeeping, and sequentially compares the timekeeping value of the timekeeping unit 6 with a comparison value preset in the comparison storage unit 7 (this comparison is performed by the host device). The distance between characters in the character string sent from On the other hand, the receiving section 4 sends a receiving output to the control section 8 every time a character is received from the host, and the control section 8 initializes the clock section 6 every time it detects the receiving output. Therefore, as long as the time measured by the timer 6 does not reach the comparison value and reception continues, the transmission remains in the standby state.

When the transmission from the host stops, the receiving output of the receiving section 4 stops, and the time value of the timer section 6 is updated one after another until it reaches the comparison value preset in the comparison storage section 7. Then, the control section 8 starts the comparison section 7 (: assuming that the set comparison value and the clock value match, and starts the transmission section 5 and transmits a response string corresponding to the received start string to the host device. Automatic logon is achieved by repeating this procedure.

As described above, according to this embodiment, there is an activation character string storage section that stores an activation string, a response string storage section that stores a response string corresponding to χ1 to the activation string, and a response string storage section that stores a response string that corresponds to a receiving unit that receives a message, a determining unit that compares the activation character string and the received character string, a transmitting unit that transmits the character string stored in the response character string storage unit, a timer unit, and a timer unit that stores a timed comparison value. A comparison value storage section that instructs the timekeeping section to start timekeeping based on a matching output from the discriminating section and initializing the timekeeping section based on a reception detection output from a receiving section, and a match between the timed value and the comparison value storage section. By providing a control unit that determines the response character string and sends the response character string from the response character string storage unit to the transmission unit if they match, the same character string may be included in multiple received character strings. Automatic logon can be performed correctly.

It is obvious that the same effect can be obtained even if this series of controls is replaced with a control means such as a microcomputer.

Effects of the Invention As described above, the present invention provides an activation string storage section that stores an activation string, a response string storage section that stores a response string corresponding to the activation string, and a system that receives a character string. a determining unit that compares the activation character string and the received character string, a transmitting unit that transmits the character string stored in the response character string storage unit, a timer unit, and a timer unit that stores a timed comparison value. A comparison value storage unit and a matching signal output when the determination unit determines that the start character string is included in the received character string instruct the timekeeping unit to start time measurement, and the reception unit receives the signal. Control to initialize the clock section based on the detection output, determine whether the clock value matches the comparison value storage section, and, if they match, extract a response string from the response string list section 1 and send it to the transmission section. By having this function, automatic logon can be performed correctly even when the same character string is included multiple times in the received character string, and an appropriate waiting time can be set for character string transmission, which has practical effects. There is something big about it.
