【Abstract】 This paper introduces a framework of the GPRS wireless data transmission system, and particularly discusses the implementation of the GPRS wireless terminal based on the MSP430 singlechip and MC35 module produced by Simens Corporation. Then Embeds the reduced TCP/IP protocol stack in the GPRS terminal, mainly including the PPP、IP、TCP、UDP and DNS protocol for our requirment. At last narrates the software designment of the system in the penetrating mode.更多还原
