Abstract

PURPOSE:To improve the function of an information processor by inputting the output information sent from a host to a printing device, and executing a communication control, based on this input information. CONSTITUTION:A communication control unit 3 being a communication adaptor is connected between a host 1 being an information processor such as a word processor, a personal computer, an electronic typewriter and a printer 2 being a printing device. When the communication control equipment 3 is not used, the host 1 and the printer 2 are connected directly. The communication control equipment 3 can be connected or removed between the host 1 and the printer 2, and the host 1 and the printer 2 can be provided with a communication function without changing them at all.

Description

[Detailed description of the invention] 1st right light” The present invention relates to a communication control device.

2. Description of the Related Art In general, there is an increasing demand for information communication in information processing devices such as document creation devices (word processors) and personal computers.

Purpose This invention has been made in view of the above points, and an object thereof is to provide a general-purpose communication control device that improves the functions of an information processing device.

Configuration In order to achieve the above object, the present invention has a function of inputting output information from a host to a printing device and controlling communication based on this input information.

Hereinafter, a detailed explanation will be given based on one embodiment of the present invention.

FIG. 2 is a block diagram showing an example of a system equipped with a communication control device embodying the present invention.

In this system, a communication control device 3 serving as a communication adapter is connected between a host 1 as an information processing device such as a word processor i personal computer or an FFI child typewriter, and a printer 2 as a printing device.

Note that when the communication control device 3 is not used, the host 1
and printer 2 are directly connected.

In this way, the communication control device 3 can be connected or removed between the host 1 and the printer 2, so that the host 1 and the printer 2 can be provided with communication functions without any changes.

FIG. 1 is a block diagram showing the configuration of this communication control device 3. As shown in FIG.

The input unit 11 receives data from a host such as a word processor or a personal computer.

The command determination unit 12 determines whether the data received by the input unit 11 is communication control information, transmission information, printer output information, etc., and transmits the input data to each unit according to the determination result.

The output unit 13 inputs printer output information 2 from the command determination unit 12, communication result output information from the transmission control unit 14, and received information from the reception control unit 17, and outputs them to a printing device (printer).

The communication control unit 14 inputs communication control information etc. from the command determination unit 12 and starts the transmission control unit 15 and reception control unit 17, and also inputs the transmission result by the transmission control unit 15 and the reception result by the reception control unit 17.

That is, it manages the communication results and sends this communication result information to the output section 13 in accordance with the communication result output information given from the host side via the command discrimination section 12.

The transmission control unit 15 stores destination address information, terminal function information, and other additional information as transmission control information from the command discrimination unit 12 in a storage unit once a day, and transmits the transmission information sent from the command discrimination unit 12. is transmitted to the other party via the protocol control unit 1 after performing necessary code conversion, and information indicating the transmission result is sent to the communication control unit 14.

The reception control unit 17 receives information sent from the other party via the protocol control unit 19, temporarily stores it in the storage unit 18, performs necessary code conversion, etc., and sends it to the output unit 13. Information indicating the reception result is created from additional information such as the terminal number sent from the terminal number, and is sent to the communication control section 14.

The protocol control unit 1 executes the communication protocol and sends the information sent from the transmission control unit 15 to the line, and also sends the information sent from the other party via the line to the reception control unit 17. .

Next, the operation of this embodiment configured as described above will be explained with reference to FIG. 3 and subsequent figures.

First, the transmission process will be explained with reference to FIG.

In this transmission process, when data from the host side is input, it is determined whether this input data is a transmission control information command. As shown in FIG. 5, this transmission control information command is rESC+E+C+n+ + -r12 +nl
and data of the number of bytes indicated by n2 (data such as destination address).

At this time, if the input data is a transmission control information command, data from the host is input, and it is determined whether this input data is a transmission information command.

This transmission information command is rEs as shown in FIG.
C+E+D'+n1. The data is sent in a format of ``data (transmission data) of the number of bytes indicated by n2-1n1 and n2''.

If the input data is a transmission information command, it determines the destination address, terminal function, etc. given by the transmission control information command described above, and sends a message to the destination address via the protocol control unit. After making a call and connecting the line, transmitting the transmission information (transmission data) received from the host using the transmission information command to the other party, and then creating a transmission record.

On the other hand, when the input data from the host is not a transmission control information command, the input data from the host side is directly output to the printer.

Next, the reception process will be explained with reference to FIG. 4.

In this reception process, there is an incoming call request from the other party, and if the call can be received, the call is processed, then information sent from the other party is received, and this received information is output to the printer.
When reception is completed, a reception record is created.

In this way, this communication control device has the function of inputting output information from the host to the printing device and controlling communication based on this long-term information.

A communication function can be added by connecting to any information processing device that can output information to a printing device.

In the above embodiment, the communication control device and the printing device are separate bodies, but the printing device can also be built into the communication control device.

Effects As explained above, according to the present invention, the functions of various information processing devices can be improved.
