用线程方式实现全双工RS232 IO的C++源代码，可以检测事件字符。代码用于SJL06T密码机，已经严密测试，确保质量。用于GPS接收机通信也是一样的。-thread used to achieve full-duplex RS232 IO C source code that can detect incident characters. SJL06T PIN code for the machine, has been closely testing to ensure the quality. For the GPS receiver communication is the same.
