Abstract

A portable data terminal equipment (DTE) with wireless telephone function, which is equipped with a memory card interface and uses EEPROM as a program memory, so it can load and execute application programs. DTE also includes an IrDA standard optical communication port or RS-232c port to achieve stronger interface capabilities. DTE provides three call origination modes (transceiver, private and public modes). As application examples, three information processing systems are disclosed.

Description

[0001] This application is a divisional application of the invention patent application with application number 97110325.9 submitted by the applicant on April 1, 1997. field of invention [0002] The present invention relates to a portable data terminal equipment with telecommunication function and an information processing system using these data terminal equipment. Background of the invention [0003] With the development of miniaturization of data terminal equipment and mobile phones, several types of portable data terminal equipment with telecommunication functions have been proposed. capable of data communication. However, for the sake of small size, these data terminal equipments are not equipped with any auxiliary memory, which makes it difficult to load application programs into the devices and make the programs run on the devices, resulting in narrowing the application range of such data terminal equipments.
