Data receiving apparatus

Abstract

PCT No. PCT / JP96 / 02980 Sec. 371 Date May 28, 1997 Sec. 102(e) Date May 28, 1997 PCT Filed Oct. 15, 1996 PCT Pub. No. WO97 / 15134 PCT Pub. Date Apr. 24, 1997A data receiving apparatus writes only a necessary part of data received via a communication network or the like in a file. Start indicating information and end indicating information located before and after character string data to be downloaded are previously stored or registered in a RAM (random access memory) of a personal computer. Character string data received via a communication control section is temporarily stored in a reception buffer, and the start indicating information and end indicating information are detected from the received character string data. Then, character string data located between the start indicating information and end indicating information is extracted from the received character string data and the extracted character string data is downloaded into a file. Since a necessary part of the received data is written in a file, the file size is prevented from increasing and a user need not instruct the start and end of the desired character string data to be received, thus significantly simplifying the instructing operation.

Description

technical field [0001] The present invention relates to a data receiving device and a data receiving method which store data received through a communication network in a file. Background technique [0002] A common communication system, either using information processing equipment such as a word processor or a personal computer connected to a telephone line via a modem or the like, or having information processing equipment serially connected together with an RS-232C or similar interface . In order to record received data, such a system stores data of a character string (hereinafter referred to as character string data) obtained through communication in a file in an external memory composed of, for example, a floppy disk drive (FDD). In the case where an information processing device is connected to a BBS (Bulletin Board System) to receive (or download) necessary information, all data from the start of announcement of reception until the end of announcement of reception i...

Problems solved by technology

[0003] Since non-essential text and control data or the like are written in a file in addition to necessary character string data when receiving information, such a commonly used data receiving device requires a large file, resulting in a decrease in memory usage efficiency

[0004] In order to receive only necessary information to prevent an increase in file size, it is necessary to precisely instruct to announce the start of reception and the end of reception, and such an instruction may cause misoperation and involve annoying operations
