tinyOS程序中可使用此代码段进行串口调试，不需要再加仿真器，很好用。-tinyOS program can use this code to carry out the serial debugging emulator do not need to add, very good to use.

stm32 usmart 通过串口在线调试程序源码编写的合理性问题，一次写入，无线仿真器即可调试(Stm32 usmart through serial serial debug program source code rationality problem, a write, wireless emulator can be debugged)
