Definitions
- a computer network such as the Internet allows a plurality of terminals, and in particular fax machines, connected to the Internet to communicate with each other by electronic mail.
- An electronic mail includes a message, consisting of a header and a body, and possibly one, or more, attachment made up of a data file which can be of various types (fax, sound, image, EXCEL, etc.).
- the message header includes a plurality of fields respectively containing a destination email address
- the transmission between two fax machines of a mail 20 containing an attachment to a fax machine is not direct.
- the mail is first transmitted over the Internet, from the sending fax machine to a mailbox in which it is stored until the receiving fax machine connects to the Internet and downloads the mail from the mailbox. letters.
- the two facsimile facsimile transmission facsimile machines do not establish duplex communication with each other over the Internet. This results in particular that the sending fax machine cannot ask the receiving fax machine to transmit its capacities or other additional information to it, as occurs during a telephone exchange protocol between two standard fax machines in the PSTN network.
- the invention therefore originates from a problem of dialogue between two fax machines over the Internet.
- the Applicant wished to be able to ask the receiving fax machine, or other receiving terminal, not only to transmit its capabilities, but also, more generally, to execute an operation for managing electronic mails.

- the mail comprising a message
- said order data is inserted into said message.
- the message of the electronic mail consisting of a header and a body, was purely informative, its role was therefore passive.
- the invention consists in having used such a message to transmit an instruction, a command, to be executed by the receiver and thus to make active the role of the message.
- command data corresponding to a request for transmission of the capacities of the receiving terminal into the mail message, so that the receiving terminal transmits its capacities to the sending terminal.
- the mail comprising a determined format file attached to the message and said message comprising a field of descriptors of the file format, said command data is inserted into said field of descriptors.
- a field is thus used to contain information describing the format of the data contained in the mail to transmit an instruction to the receiving terminal, to remotely control the receiving terminal.
- the invention also relates to a terminal for implementing the above method, comprising means for receiving electronic mails and means for executing management operations, characterized in that it also comprises means for searching the meaning of control operation execution data inserted in a received mail and means for triggering, if necessary, the execution of said management operation under said command.

- Example 3 Sending the capabilities of the sending fax machine
- the automaton 14 ′ inserts, in the descriptor field of a mail message to be sent, a command word for recording capacity and, in a field of associated information, the capabilities of the sending fax machine 30. Then the sending fax machine 30 sends the mail to the receiving fax machine 40.
- the input 23 enters the command word
- the identification machine 22 searches for its meaning and identifies it with a capacity recording command
- the input machine 24 captures the capacities of the sending fax machine 30 and, under the command of the central unit 1, the automaton 11 stores them in the directory of correspondents 9.
- Example 4 Requesting capacities from the receiving fax machine
- the machine 14 under the control of the user, the machine 14 'inserts a command word for transmitting the capacities of the receiving terminal 40 into the descriptor field of the message of the mail to be sent, and the facsimile machine 30 sends the mail to the receiving terminal 40.
- the input machine 23 enters the command word
- the identification machine 22 searches for its meaning and identifies it with a capacity transmission command and, as in In example 3, the automaton 14 prepares a mail containing in a descriptor field a command for recording capacities and, in an associated information field, the capacities of the receiving fax machine 40.
- the facsimile machine 40 sends the mail to the sending facsimile machine 30 in which the capacities of the facsimile machine 40 are recorded in the directory of the correspondent 9 ′, as explained in Example 3.
- Example 5 Request for forwarding to another receiving fax machine
- the machine 14 In the sending fax machine 30, under the control of the user, the machine 14 'inserts a forwarding control word on another receiving fax machine and the electronic address of this other receiving fax machine, respectively in the descriptor field and in an associated information field of the message of a mail to be sent.

- the sending fax machine 30 sends to the fax machine receiver 40 a mail containing a message to which is attached a data file having a determined format such that the facsimile machine 40 is not capable of reading and therefore of editing, of restoring, the file.
- the message header here contains a file format MIME descriptor field.
- the connection automaton 25 connects to the Internet 100, the reception automaton 20 downloads the mail and stores it in the working memory 18.
- the automaton 21 for determining file formats scans the descriptor field, enters the MIME descriptors of the format of the file attached to the message, deduces therefrom that the facsimile machine 40 is unable to restore the file and signals it to the central unit 1.
- the latter then commands the input machine 24 to enter the electronic address of the sending terminal 40, in the source field of the message, and supplies this address as well as the text of acknowledgment of non-understanding stored in the memory 13 to the automatic mail preparation machine 14.
- L PLC 14 prepares an electronic mail containing, in a destination field, the address of the sending fax machine 30, in the source field, the address of the receiving fax machine 40, in the subject field, an access keyword used of non-comprehension, recognizable automatically by the sending fax machine 30, and, in the body of the message, the text of acknowledgment of non-comprehension. Then, the mail is encoded, stored in the sending memory 16 and sent by the sending machine 17 to the sending fax machine 30, through the Internet 100. The mail containing the unreadable file and the mail containing the acknowledgment of non-comprehension are downloaded and transmitted respectively, during the same connection to the Internet 100.
