Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dial transmitting device such as a modem for connecting a terminal device such as a personal computer to a telephone line.

[0002]

2. Description of the Related Art When document data or the like is communicated from a terminal device such as a personal computer using a telephone line, it is performed via a dial transmitting device such as a modem. In this case, the terminal device generally has a so-called redial means for automatically redialing after a predetermined time if the communication line with the partner is not connected when dialing. The redial is performed a set number of times at a set time interval on the terminal device side.

[0003]

By the way, when this terminal device is connected to a telephone line through a dial transmitting device such as a modem, there are legal restrictions on redialing. In other words, when redialing,
Except in the case of fire, theft, etc., the redial interval is limited to 3 minutes within 2 times.

However, when the terminal device itself has a redialing means, the redialing interval and the like complying with the above rules are preset, but the redialing set by the terminal device side is changed by the user. It is also possible. Further, when the user purchases and uses commercially available software for communication, the user may be able to set the redial interval or the like independently, and the user may not even know that the above regulation exists. Therefore, the former and the latter sometimes communicate with each other without knowing whether they comply with the above rules.

Further, since the dial transmitting device is merely a device for connecting the terminal device to the telephone line, the dial transmitting device side does not have the function of managing the redial interval. Therefore, since the redial interval depends on the terminal device as described above, no check has been made as to whether or not the above rules are complied with.

Therefore, the present invention solves the above-mentioned problems and proposes a dial transmission device such as a modem capable of managing the redial interval set on the terminal device side.

[0007]

In order to solve the above-mentioned problems, the present invention has redial means for automatically redialing after a predetermined time if the communication line with the other party is not connected when dialing. A redial transmission device such as a modem for connecting a terminal device such as a personal computer to a telephone line, and when a redial is made from the above terminal device, it is judged whether or not this redial interval has passed a predetermined time. When the redial interval is judged to be inappropriate, the redial command from the terminal device side is invalidated.

[0008]

In FIG. 1, when the terminal device 1 such as a personal computer having the redial means 11 sends document data or the like to the telephone line 3 through the dial transmission device 2 such as a modem for communication, the terminal device 1 dials at the time of redialing. It is determined whether or not the interval between the dial commands 12 sent to the transmitting device 2 is equal to or longer than the predetermined redial interval set by the redial interval determining means 21 provided in the transmitting device 2.

When the interval between the dial commands 12 is equal to or longer than the predetermined redial interval set by the redial interval determining means 21, dial transmission is executed. If it is less than the predetermined redial interval set by the redial interval determination means 21, the dial command 12 is invalidated, dial transmission is not executed, and the terminal device 1 side is set according to the procedure of the redial means 11. When the timer value is reached, the redial process is performed again.

Therefore, it is possible to legally manage the redial interval set on the terminal device side 1 on the transmitting device 2 side.

[0011]

Next, an embodiment of a modem according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a system diagram of a dial transmitting device such as a modem according to the present invention. In the figure, reference numeral 1 is a terminal device 1 such as a personal computer, which has a redial means 11 for automatically redialing after a predetermined time if the communication line with the other party is not connected when dialing.
A dial command 12 is sent to a dial transmitting device 2 which will be described later, based on a dial command from the terminal or a redial command from the redial means 11 of the terminal device 1.

Reference numeral 2 is a dial transmission device such as a modem,
The redial interval determining means 21 has a redial interval determining means 21, and the redial interval determining means 21 determines whether or not the interval between the first dial command 12 and the next dial command 12 is equal to or longer than a preset predetermined time interval. If the interval of 12 is equal to or longer than the set time, the dial transmission to the communication line 3 is executed according to the dial command 12. If the interval between the dial commands 12 is less than the set time, the dial commands 12 are invalidated and the dial transmission to the communication line 3 is not executed. In the case of this example, the time setting of the redial interval determination means is set to 60 seconds as an example.

FIG. 2 is a flow chart for explaining the procedure of this redial interval determination. First, when there is a dial command from the terminal device 1 side, when the dial command 12 is transmitted (step 41), the dial transmitting device 2 side recognizes the dial command 12 (step 5).
1), the redial interval is determined (step 5)
2). In the case of this example, the time setting of the redial interval determination means is set to 60 seconds as an example, as described above,
The timer value is compared to 60 seconds. However, when the timer value is 0 second, it is determined that the first dial command 12 has arrived, and the process proceeds to the next step 53. If the timer value is 1 second or more and less than 60 seconds, the next dial command 1
It will be in a state of waiting until 2 arrives.

In step 53, dial transmission is executed and a timer for measuring the redial interval is started. After this dial transmission, it is judged whether or not there is a response from the partner station (step 54), and if the partner station can be accessed, the communication mode is set and the timer for measuring the redial interval is cleared (step 55). At this time, the terminal device 1 side also enters the communication mode, and the document data and the like can be transmitted from the terminal device 1 to the partner station using the communication line 3 (step 43).

If there is no response from the partner station in step 54, the system waits until the next dial command 12 arrives. The timer for measuring the redial interval keeps counting. On the terminal device 1 side, it is determined whether the communication mode has been entered (step 42), and the process proceeds to the next step 43. When the timer value set by the redial means 11 is reached, the redial processing is performed again according to the procedure of the redial means 11. Done.

Next, when redialing is performed by the redialing process (step 44), the dial command 12 is sent again to the transmitting device 2 side (step 41). This dial command 12 is recognized by the dial transmitting device 2 side (step 51), the timer value at this time is recognized as a redial interval, and it is compared with a predetermined set value of 60 seconds (step 52). When the timer value is 1 second or more and less than 60 seconds, the above-mentioned steps after step 56 are performed. At this time also, the timer for measuring the redial interval on the transmitting device 2 side continues to count, and each time the dial command 12 arrives, the timer value and the predetermined set value of 60 seconds are compared and judged to determine the timer value. Repeats the above steps 52 and 51 until exceeds the predetermined set value of 60 seconds.

When the timer value exceeds the predetermined set value of 60 seconds, the above-mentioned steps after step 53 are executed this time. At this time, the above timer is cleared and the timer starts counting anew.

In the above-described embodiment, the set value of the redial interval determination means of the dial transmission device 2 is set to 60 seconds, but it can be changed and set appropriately in accordance with the legal regulation and in the usage state. It can also be applied to a fax machine or the like as a dial transmission device.

[0020]

As described above, according to the present invention, the redial interval set on the terminal device side 1 can be legally managed and managed on the transmitting device 2 side.

Therefore, even if the user purchases and uses commercially available software for communication and the user independently sets the redial interval and the like, even if the user does not know that the above regulation exists, it is legal. There is an effect that communication can be performed in compliance with.
