Description

[Detailed description of the invention] When transmitting data using a telephone line, the auto-dialing function of conventional modem interfaces does not allow the transmitting user to receive an audio message when the other party is busy. Otherwise, the user is only notified on the display, and the user has to disconnect from the interface and make a new call.

Therefore, even if there is an auto-dialing function, operation is complicated, especially when sending data to a large number of parties.

This invention attempts to solve these problems.

Let's explain one example below.

In FIG. 1, numeral 1 indicates a signal source of data to be transmitted and a control circuit that controls the transmission thereof. In this example, the circuit 1 is constituted by a personal computer, has data to be transmitted, and has, for example, a program shown in the flowchart shown in FIG. 2 loaded or written therein in order to control the transmission.

Further, 2 indicates a CRT display, which is connected to the computer 1 and displays processing results and the like. Further, numeral 3 indicates an RS-232C circuit, which converts the transmission data from the computer 1 from parallel to serial, and also performs access to various control signals for transmission. Further, 4 is a modem for converting transmission data into an audio signal, 5 is an interface having an acoustic coupler and dialing function, and 6 is a telephone line.

In the flowchart of FIG. 2, the following processing is performed when transmitting data. That is, this program starts from step [11] and proceeds to step [12], and in step [12], for example, a table as shown in FIG. 3 is created. That is, in this table, the first column (from the left) is the reference number N, the second column is
The column shows the telephone number of the recipient, and the third column shows the priority order ORD of the transmission, and the orders ORD are grouped according to the same priority order. Furthermore, the fourth column shows a transmission flag FLG that indicates whether data has been transmitted to the other party.If data has not been transmitted, FLG="0"; if data has been transmitted, FLG is "0".
FLG="1".

This table, except for the flag FLG, is loaded into the work area of the RAM of the computer 1 from an external storage device, such as a floppy disk device (not shown), or is stored in a non-volatile memory in the computer 1 in advance. is,
It is configured based on what is written in this. At this time, it is assumed that this table is sorted in the order of priority ORD.

Also, the flag FLG is the RAM of computer 1.
This is configured in the work area, and all are initialized to "0" in step [12].

Then, following step [12], the process proceeds to step [13], and in this step [13], the user inputs whether to send data up to the priority level ORD (priority level LVL).

Then, the process proceeds to step [14], where the loop counter CNT is set to CNT="1", and
Next, in step [15], the reference number N is changed to N=1
is set to

Furthermore, the process moves to step [16], where the priority order ORD corresponding to the number N at this time is retrieved from the table in FIG. 3, and this order order ORD is compared with the priority level LVL input in step [13]. If ORD≦LVL, proceed to step [17],
If ORD>LVL, proceed to step [23].

Then, in step [17], the flag corresponding to the number N at this time is
FLG is taken out and checked, FLG="0"
If so, proceed to step [18], and if FLG="1", proceed to step [22].

Then, in step [18], the telephone number corresponding to the number N at this time is retrieved from the table in FIG. 3, and a call is made to the other party using this telephone number. It is determined whether or not the other party is on the phone, and if the call is in progress, proceed to step [22]; if not, proceed to step [20], data is sent to the other party in this step [20], and then step [21] is entered. ]
, the flag corresponding to the number N at this time
FLG is set to "1" and the process advances to step [22].

In this step [22], the number N is incremented by "1" and then jumps to step [16].

Therefore, according to the above routine, data is sent to the other party whose priority level is higher than the priority level LVL input in step [13] (ORD≦LVL) and who is not currently on a call. The flag FLG corresponding to the sender is “1”
It will be set to . Further, data is not being sent to the other party who was on the phone, and the corresponding flag FLG is "0".

Then, when the above processing is completed for the opponent with ORD≦LVL, ORD
>LVL, so step [23] is executed after step [16].

In this step [23], the counter
CNT is incremented by "1", and then in step [24], the value of counter CNT is compared with a predetermined value LIM, and if CNT≦LIM, proceed to step [15], and if CNT>LIM, proceed to step [25]. Proceed to.

Therefore, through steps [23] and [24], the processes from step [15] to step [22] are performed a predetermined number of times LIM. In other words, the priority level is higher than the priority level LVL, and
The operation of transmitting data to the other party who is not on a call is performed only LIM times, and at this time,
From the second time onwards, data will not be sent to the other party to whom data has been sent once based on the flag FLG, and data will be sent only to the other party to whom data has not been sent yet because they were on a call last time.

When the above operations are completed, the display 2 displays in step [25] that data has been sent to all parties whose priority level is LVL or higher and who are not currently on the phone.

Thus, according to this invention, when transmitting data to a large number of parties using a telephone line, even if there is a party on the phone, the data can be easily transmitted without the need for complicated data collection. Can be sent. Furthermore, the priority order ORD of the other party can be easily changed depending on the content of the data to be transmitted.
