BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to data communication of a computer, and more particularly to a portable portable device such as a PHS capable of wireless communication.

[0002]

2. Description of the Related Art In recent years, computer data communication has been in the spotlight. In the past, most of these methods generally used a modem (MODEM). However, as various digital wireless voice communication systems have been developed, attempts have been made to utilize them for data communication of portable notebook personal computers.

[0003] A conventional data communication system will be described below. FIG. 5 is a diagram of a first conventional example showing a circuit configuration of data communication by a wired modem system and its connection.

In FIG. 5, reference numeral 501 denotes a personal computer;
503 is a modem device, 503 is a communication circuit block for exchanging communication with the modem device 502 in the personal computer 501, 50
Reference numeral 4 denotes a cable for connecting the communication circuit block 503 in the personal computer 501 to the modem device 502, reference numeral 505 denotes a telephone network, and reference numeral 506 denotes the modem device 502 and the telephone network 505.
507 is a modem device of the data communication partner, 508 is a cable connecting the modem device 507 of the data communication partner to the telephone network 505, 509 is a personal computer of the data communication partner, and 510 is a personal computer 509 of the data communication partner. 511 is a communication circuit block for exchanging communication with the modem device 507 of the personal computer 5.
A cable 512 for connecting the communication circuit block 510 in 09 and the modem device 507 is a data flow.

The telephone line network 505 can be of two types: an analog type and a digital type. Data transmitted from a personal computer when data is passed through a line is converted into a digital signal (DAC).
Analog converter).

Considering the manner of data communication through an analog telephone line in the first conventional example, the operation of the data communication apparatus configured as described above will be described below.

First, when it is desired to transmit data, the personal computer user performs an appropriate operation to transmit the created data (text, image, numerical value, etc.) to the modem device 502.
01.

For example, a GUI (Graphical User

The modem device 502, which has received the data transmitted from the third device to the modem device 502, secures the telephone line network 505 based on a suitable communication protocol with the other modem device 507 to be transmitted.

[0010] After both sides confirm that the line is secured, the modem device 502 converts the digital data into the analog system of the telephone line network 505 and transmits the data to the telephone line. The modem device 507 that has received the data converts the analog data into digital data and transfers the data to the communication circuit block 510 in the personal computer 509.

The communication circuit block 510 that has received the digital data stores it as a file in the personal computer 509, and completes the communication. The communication partner displays the data received as a file on the screen or the like of the personal computer 509 and confirms the contents (there are various methods depending on the application installed in the personal computer).

The data flow 512 at this time is summarized as follows.
First, data passes from the communication circuit block 503 of the personal computer 501 to the modem device 502 via the cable 504. Next, from the modem device 502 through the telephone line 506 via the telephone line 506, it passes from the other party's cable 508 to the other party's modem device 507. Further, the communication circuit block 510 finally transmits the personal computer 509 through the cable 511.
Is taken in.
