VxWorks RTOS具有良好的裁剪能力，用戶可通過交叉開發環境根據需求裁剪組件，選擇各種內核組件進行系統內核配置，編譯系統內核時進行獨立的加載和卸載．VxWorks RTOS提供了RAW MODE和LINE MODE兩種串口工作模式，通過I／O 控制函數Ioctl()對串口參數進行選擇，通過Select宏實現對串口數據讀寫與監測． 通過配置頭文件中相應的配置宏來實現該系統的串口通信．VxWorks RTOS 支持x86、Power PC、68K、CPU32、SPARC、i960等多種平臺． 并以x86平臺為例，介紹基于x86平臺的嵌入式VxWorks系統與PC機串口通信的實現方式以及串口通信的編程方法．

VxWorks RTOS has superior clipping ability．User can clip down groupware on the basis of requirements by using the Tornado cross-development environment．User configures kernel facilities of System by selecting some of the KerneI facilities，and all kernel facilities can be independently configured into the system．VxWolrks RTOS provides two serial port work modes of RAW-MODE and LINE_MODE．User can select serial port parameters by using the ioctl()routine，and can read，write and monitor serial ports through Select macros．The serial communication of system is realized threlugh configuring corresponding macros．VxWorks supports all kinds of operating platform，such as x86，Power PC，68K，CPU32，SPARC，j960 and so on．The realization ways and programming method of serial communication between embedded VxW orks system of X86 operating platform and PC was introduced．
