用VC++开发的对GPRS-MODEM控件的简单使用，GPRS-MODEM一般工作在串口，速率为115200 可以收发短信-VC development of GPRS-modem controls simple to use, GPRS-modem serial port in general, the rate of 115,200 can send and receive text messages

该代码是在VC++6.0环境下控制串口采用RS232协议读写的小工具，可以通过AT指令驱动Modem进行拨号等操作。-The code is a serial RS232 protocol read and write control VC++6.0 environment gadget can be driven through the AT command modem dial-up and other operations.

VC下面开发的串口发短信程序,基于AT指令的GSM MODEM-The VC following serial texting program development, MODEM AT
