Abstract

The radio access-to-Internet card includes PCMCIA interface management chip, RS232 interface management module, power source managing circuit, audio management module, SIM card managing module, baseband module and RF circuit. The baseband module and the RF circuit are connected separately the RS232 interface management module, the power source managing circuit, the audio management module and the SIM card managing module; the power source managing circuit is connected to the RS232 interface management module; and the PCMCIA interface management chip is connected to the RS232 interface management module and PCMCIA interface circuit. The present invention aims at overcoming the inconvenience of using GPRS radio module in embedded system and making full use of PC.

Description

Technical field [0001] The present invention relates to how to use the wireless GPRS module on the PC to realize multiple key technologies for the user to make calls, send and receive short messages, and dial-up the Internet through Windows programming, especially relates to the use of the wireless GPRS module on the PC in the (communication) field programming techniques. Background technique: [0002] At present, wireless GPRS modules are mostly used in mobile phone production, business phones, and vehicle-mounted terminals, and these systems are mostly embedded operating systems. Usually, these systems have defects such as slow CPU speed, less available resources, and inconvenient input and output. . And at present along with the continuous popularization of PC, the continuous improvement of operating speed, the convenience of operation, especially the continuous popularization and development of notebook computers have brought great convenience for people. Invention co...
