Abstract

PURPOSE:To mutually connect personal computers provided at a transmitting and a receiving terminals at a high speed and without being conscious of the communicating procedure by having originally the communicating procedure as an adapter and using the facsimile equipment incorporating a highly speedy MODEM. CONSTITUTION:Between a telephone line network 3 and a transmitting side personal computer (PC) 1, and the telephone line network 3 and the receiving side personal computer (PC) 5; facsimile equipnents (FAX) 2 and 4 are respectively connected as the adapter. First, the transmitting side PC1 is sent to a FAX 2. The FAX 2 sends a transmitting starting signal SS to an opponent FAX 4. The FAX 4 transmits a receiving response signal RR to the FAX 2 when the SS is received. The FAX 2 sends a transmitting response signal SR to the FAX 4. Thereafter, the FAX 2 sends the accumulated data to the FAX 4. Thus, the data continue to be transmitted, and when the data run short, the FAX 2 sends a transmitting completion signal SE to the FAX 4.

Description

[Detailed Description of the Invention] [Summary] Paragraph 1 is a communication booster that uses a facsimile machine as an adapter to enable high-speed communication between personal computers without requiring a data terminal communication procedure. This is what we do.

[Industrial application field]

The present invention relates to a personal computer communication system. Generally, when communicating between computers using a telephone line network, the personal computer serving as a data terminal does not have any internal communication procedures, so there is no communication between the sending side computer and the telephone line network, and between the receiving side computer. An adapter with a certain procedure must be installed between the terminal and the telephone network.

The present invention relates to a personal computer 1lfl borrowing system in which the adapter is constituted by a facsimile machine.

[Conventional technology]

Conventionally, there has been a first method that uses an acoustic coupler as an adapter, and a second method that uses a high-speed modem.

The first method can be used for data terminals without communication procedures, and the second method is used for specific communication networks characterized by high-speed data.

[Problem that the invention seeks to solve]

However, the method using the first acoustic coupler among the conventional techniques described above has a problem in that the transmission speed is about 300 bps and cannot be applied to higher speeds.

In addition, when applying the second method using a high-speed modem to a general telephone line network, procedures such as confirming the other party are required, and a new communication procedure must be set for the data terminal. There is a point.

[Means for solving problems]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a personal computer communication system that enables high-speed communication and does not require a communication procedure at a data terminal.

As shown in FIG. 1, the means for this purpose is to connect facsimile machines 2 and 4 as adapters between the telephone line network 3 and the sending side personal computer 2, and between the telephone line network 3 and the receiving side personal computer 5, respectively.
is connected.

[Function] As described above, according to the present invention, since a facsimile machine which originally has a communication procedure as an adapter and has a built-in high-speed modem is used, computers installed at the transmitting and receiving ends can be connected to each other at high speed while being aware of the communication procedure. can be interconnected without having to do so.

Therefore, it is possible to provide a high-speed personal computer communication system that does not require any procedures.

〔Example〕

The invention will now be explained by way of example with reference to the accompanying drawings.

FIG. 2 is a diagram showing an embodiment of the present invention.

Which facsimile device is used in this example?
ZFAX falls under Group 3 (G3) when classified based on data transmission speed, etc., and is the most common device as a terminal interface.

This facsimile machine interconnects personal computers, which do not have internal communication procedures, through a general telephone line network.

First, we agree that we will communicate with each other's computers through telephones connected to facsimile machines. Next, press the communication button on the receiving facsimile machine to enter the receiving state.

In this state, the sending personal computer 1 sends the data to its facsimile machine (FAX) 2 (■).

After confirming that it is connected to the telephone line network 3, the FAX 2 sends a transmission start signal SS to the destination FAX 4 (■).

When the FAX 4 receives the SS, it transmits a reception response signal RR including modem capability information (transmission speed), etc. to the FAX 2 (■).

The FAX 2 sends a transmission response signal SR to the FAX 4 indicating that data will be transmitted at a predetermined speed (for example, 9600 bps) based on the information from the FAX 4 (■).

After that, FAX 2 stores and transfers the data to the FA.
Send to X 4 (■).

If an error occurs in the received data on the way, F^χ4 notifies FAX 2 of the error by some means, and the transmission is repeated again.

Data continues to be transmitted in this manner, and when there is no more data, the FAX 2 sends a transmission end signal SE to the FAX 4 (■).

This will end the communication between the faxes, and the fax 4
sends the received data to the personal computer 5 (■).

In the above, a binary code procedure is used for procedure signals other than data transmission, and the signals are transmitted using the V21 channel modulation method. Further, data transmission uses V29 or V27 Ter.

Therefore, by providing a communication procedure only between facsimile machines, high-speed data communication using a V29 or V27Ter modem is possible between personal computers that do not have a built-in communication procedure via a general telephone line network.

[Effects of the Invention] As described above, according to the present invention, since a facsimile machine that originally has a communication procedure and a built-in high-speed modem is used as an adapter, it is possible to communicate between PCs installed at the sending and receiving ends at high speed and also with a communication procedure. They can be interconnected unconsciously.

Therefore, it is possible to provide a high-speed personal computer communication system that does not require any procedures. Furthermore, it also has the effect of being easy to implement.

Claims (1)

[Scope of Claims] In a method for communicating between two personal computers via a telephone line network by providing adapters between the sending side personal computer and the telephone line network and between the telephone line network and the receiving side personal computer, each of the above-mentioned Using a facsimile machine as an adapter, data is first stored from the sender's computer to the sender's facsimile machine, and then the communication procedure is carried out only between the two facsimile machines and the data is sent from the sender's facsimile machine to the receiver's facsimile machine. A personal computer communication system characterized in that the data stored in the receiving facsimile device is finally transmitted to the receiving personal computer.
