Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an e-mail system comprising a terminal Z1, a host I computer, and a network connecting these.

BACKGROUND OF THE INVENTION Electronic mail systems based on message handling systems (Ml(S)) are becoming popular.

This system is a computer interface between the terminal and the host computer.
- Various services are realized by exchanging role documents (CDs).

For example, the host computer periodically sends CI) to the terminal, and the terminal status at that time is sent to the host computer.
There is an e-mail system that performs terminal monitoring service that is notified by D. There are also e-mail systems that implement functions such as circular, confidential, and bulletin board functions on the host computer side.

(Problem to be solved by the invention) However, in the periodic diagnosis as described above, CI) is exchanged at a fixed period for all terminals regardless of the operating status of the terminal, so Terminals that are not working will be wasted, while terminals that are used in large quantities may be running out of paper, but the host computer will not know about this until the next regular checkup. The problem was that I couldn't do it.

In addition, the number of facsimile terminals that temporarily store documents on a disk and receive them sequentially has increased recently, but since the operation and transmission operations of these facsimile terminals are performed asynchronously, the following problems arise. there were.

In Ml-IS, destination information is sent on a CD before the document is sent, but if the destination entered in the operation is SL and is not defined in the e-mail system, the communication is treated as an error. However, after the operation has already been completed and the operator has left, the sending operation occurs and the error is passed, so it is much too late for the operator to notice the error in the destination specification, and the error notification is also delayed. I had to print it out and save it.

The present invention has been made in view of these points, and its purpose is to provide an e-mail system that can quickly and efficiently know the status of a terminal, and can also immediately know if there is an error in specifying a destination. It's about doing.

(Means for Solving the Problems) In order to achieve the object described above, the first invention of the present invention provides a system that includes a group of terminals, a host computer, and a terminal 11Y' described in 01j.
In an e-mail system consisting of a network connecting a computer and a host computer, each terminal has means for notifying the host computer of the completion of printing of the received message 71), and a means for notifying the host computer of the completion of printing of the received message 71), and a means for notifying the host computer of the completion of printing of the received message 71), and a means for notifying the host computer of the completion of printing of the received message 71), and a means for notifying the host computer of the completion of printing of the received message 71), and a means for notifying the host computer of the completion of printing of the received message 71), and means for editing the read state value into i) 1 Chondral sequence 1.

Further, a second invention of the present invention provides a control document for checking destinations at the end of a sending operation in an e-mail system comprising a group of terminals, a host computer, and a network connecting the group of terminals and the host computer. a first channel for transmitting and receiving a document; and a second channel for transmitting and receiving a control document and a document asynchronously with the first channel are provided between the host computer and the terminal; Con1~Roll Dokiyumen for checking the destination by channel!・Means for transmitting only the data to the boss computer at the end of the sending operation; means for analyzing the destination check result in the host computer using the receiving controller 1~role document to determine whether there is an error; The system is equipped with a means for stopping the accumulation of documents and for notifying an error.

(Operation) In the e-mail system according to the first aspect of the present invention, each terminal reads the status of its peripheral equipment and edits the read status (i() into a condor document I. Then, the completion of printing of the received document is passed to the host computer using the control document.This allows the value representing the terminal status to be edited at the time of printing completion, and the terminal information is sent to the host computer according to the operation of the terminal. Status can be notified.

Furthermore, in the e-mail system according to the second technology, the terminal sends only a control document for checking the destination to the host computer at the end of the sending operation through the first channel, and Receive destination check results Check whether there is a control document error, and if there is an error, store the document IJ
Stops i and sends an error notification. Further, the second channel sends and receives the control document and the document asynchronously with the first channel. As a result, the destination is checked immediately after the sending operation is completed, and the operator can immediately know of any errors caused by incorrect specification.

Each of the terminals has a means for notifying the host computer of the completion of printing of the received document using a control document, a means for reading the status of peripheral devices of the terminal, and a means for notifying the read 0(
By being equipped with a means for editing the value of the 1st letter in the 1st note control document, it is possible to edit the value representing the terminal status when printing is completed, and the terminal is sent to the host computer according to the operation of the terminal. Since the status of the terminal can be notified, the host computer can better understand the status of the terminal, and the host computer can quickly respond to terminal failures.

Further, a second invention of the present invention provides a control document for checking destinations at the end of a sending operation in an e-mail system comprising a group of terminals, a host computer, and a network connecting the group of terminals and the host computer. The control document 2 channel and the first channel are provided between the boss computer and the terminal, and each terminal can use the first channel to check the destination. A means for transmitting only a control document to the host computer, 0 at the end of the transmission operation, and a means for receiving the destination check result at the host computer, and storing the document if there is an error. By providing a notification means, the destination is checked immediately after the sending operation is completed, and the operator can immediately know of an error due to the 11'+i specification.
Since it is possible to send and receive only control documents to and from the destination disk, there is no need to make any changes to the Korg or decoder. Furthermore, the error results can be displayed in real time or the like, and in this case there is no need to print out the error notification.
