The provider type corresponds to the provider type in the user table T2, and identifies a different login procedure for each provider. For example, when one provider has a plurality of telephone lines or when a plurality of providers are used, it is possible to register for each telephone number and select it at the time of transmission.

A procedure for transmitting an electronic mail to the Internet will be described. The protocol uses the following at each layer of the OSI reference modem:

[0026]

[Table 1]

First, the login procedure will be described. As shown in FIG. 4, when a line with a provider computer (hereinafter, referred to as a server) is set, the communication terminal device, for example, receives a PAP (Password Authentication Protocol).
According to l), keep sending the user ID and password until an Ack or Nack is received from the provider. Nack
After receiving, release the line and redial. Upon receiving the Ack, login to the server is completed.

After completing the log-in to the server, an e-mail is transmitted by SMTP as shown in FIG. First, the communication terminal device makes an SMTP connection request to the server. If the server can be connected, the server returns a response code 220 to the communication terminal device. Further, if the communication terminal device is "HEL
When the server recognizes the domain name of the communication terminal device, the response code 250 and the domain name of the server are returned. After that, the communication terminal device transmits the mail and completes. Then, "QUII
In response, the server returns a response code 221 and the SMTP is terminated. After the transmission of the e-mail is completed, the server logs in and opens the line.

Next, the operation of the communication terminal of the present invention when receiving a mail will be described with reference to the flowchart of FIG.
Call a contract provider and log in (S1), and check if there is a received mail (S2). If there is no received mail, log out and release the line (S
7).

On the other hand, if the received mail exists, the electronic mail is sequentially received (S3), and the sender address is extracted from the "From:" line included in the header information of the received mail and stored in the RAM 7. (S4). If the user has requested the printout of the source address, this is printed out (S5). The above steps S3 to S5 are repeated until all the mails have been received (S6). When all the mails have been received, the user logs out and opens the line (S7).

The communication terminal device is generally provided with keys called speed dials and one-touch keys, and the user preliminarily registers a telephone number of a communication destination or the like with the speed dial or one-touch keys. By making it possible to call the other party with a small number of key inputs, it is possible to save time and effort for input and to avoid input errors.

A process for transmitting an e-mail to the address 1 is performed.

On the Internet, G3 format image data cannot be transmitted directly, and is converted to an e-mail format as follows. The image conversion unit 22
TIFF CLASS F header information is added to the head of the G3 format image data to create TIFF image data (S25). Since the TIFF image data is binary data, the binary / text converter 23 converts it into text data (S26).

Further, the mail editing unit 24 adds an e-mail header to the TIFF image data converted to the text data (S27). This header contains at least "From:", "To:", "Subject:" items. "From:"
Indicates the Internet e-mail address of the user selected from the user table T2, and "To:" indicates the Internet e-mail of the destination selected from the history information.
In the i1 address, "Subject:", "TIFF (G3)" indicating that the electronic mail includes image data in TIFF format
Set.

When the data in the e-mail format is completed, a dial-up connection to the Internet is made. The type (analog / digital) of the line of the provider selected from the provider table T3 is determined.
Set the modem 10, and if it is a digital line, DSU9
Set. Make a call to the telephone number of the selected provider, press the send key (start key) and wait for a response (S
28).

When the telephone line with the provider is set,
The user logs in according to the above-described PAP, and transmits an e-mail by SMTP (S29). After transmission is completed, log out and release the telephone line.

In this embodiment, a case has been described in which black-and-white binary image data is converted into an electronic mail format and transmitted. However, the image data is not limited to this. For example, black-and-white multi-valued and color image data may be used. , TIFF image data. In addition, electronic mail can be transmitted to the Internet even for data other than image data, such as audio and moving images.

The computer communication network is not limited to the Internet, but may be any computer communication network capable of transmitting and receiving e-mail, and the same effects as those of the present embodiment can be obtained.
