这是我自己写的关于串口通讯的小程序,适于两台PC机之间通过(交叉串口线)串口通讯.可以(自动或手动)发送数据、接收数据、保存数据。是调试串口和初步学习串口编程的好例子。其中还用到了典型的串口类，对于从事串口编程者有一定的借鉴作用-This is my own writing serial communication program, suitable for between two PC through serial communication (null modem serial cable)

周立功的ucos驱动中间件，包含串口、modem、iic、spi和文件系统等代码-ucos driven middleware writen by ZhouLigong, including serial, modem, iic, spi, and file system code

atmega16通过模拟串口协议控制msm7512通信芯片，进行传递音频数据，实现远程电话线控制功能，模拟modem。-by simulating atmega16 serial communication protocol control msm7512 chip pass audio data, remote phone line control function, an analog modem.
