imode手机application编程-Codeing for Imode Cell phone Appliction

Very Low Frequency (VLF) spectrograms show sometimes sets of lines called MLR (Magnetospheric Line Radiation) with frequency spacing close to 50 or 60 Hz. It is very tempting to attribute these MLR to Power Line Harmonic Radiation (PLHR). PLHR are the ELF and VLF waves radiated by electric power systems at the harmonic frequencies of 50 or 60 Hz. Here we show for the first time large scale MLR observed simultaneously on ground and on board a low altitude satellite which is flying over the same zone.

串口通讯,用控件做的，可以做串口调试。这是我网上下载的，希望多大家有帮助。-VC++

开发工具Keil ，采用单片机C8051F340。主要实现功能，通过485级联通信，采取上位机（串口调试软件）发码的方式，给各从机发指令，每个从机有固定的地址，从机接到指令后进行相应的操作并返回一串码。若发送的码有误，则返回错误指示码。
