原创：xmodem协议介绍及VxWorks下的应用最初，XMODEM协议是一种基于调制解调器直接拨号通讯的文件传输协议，用来支持两台计算机之间的文件传输。。由于其简单可靠、实现方便的特性，现在已经广泛应用于嵌入式设备中。实现xmodem只需要微处理器带有串口控制器就行了，一般的8位单片机SCM也能进行文件传输。

-Original: xmodem protocol introduced and VxWorks Initially, XMODEM protocol is a direct modem dial-up communications-based File Transfer Protocol, used to support file transfers between two computers. . Because of its simple, reliable, convenient features, and is now widely used in embedded devices. Achieve the xmodem need only microprocessor with a serial port controller on the line, the general 8-bit microcontroller SCM can also transfer files.
