Securities Pda Communications Program Design And Implementation

Since entering 1990s, the world has come into information age. It is the trend that people have various and professional needs for information. The requests for every kinds of information acquiring tools have been enhanced. It requests that these tools are rapid, exact, real-time and convenient to acquire infonnation. At the same time, these tools are easy for carrying. In this situation, the factories have devised various information terminal equipments adapt to the needs of people. In all information terminal equipments, the palmtop computer has the best advantages, especially the professional palmtop computer. So it is a modem social demand to research and develop a kind of terminal equipment, professional palnitop computers, which is inexpensive and easy to use. These products can receive not only common information but also stock information. Professional palmtop computers achieve improvement based on common palmtop computers. At first it receives stock information by receiving circuitry of RFR machine, then the SCM (Single Chip Microcontroller)system communication programs decode and send information to common PDA system communication programs, at last these information are used to output by higher stock information analyzing programs after been parsed. This paper discusses each main aspect to realize the stock PDA system communication programs.
