Realization of Serial Communication in Embedded Real-Time VxWorks Operating System

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 Kernel facilities, and all kernel facilities can be independently configured into the system. VxWorks 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 through configuring corresponding macros. VxWorks supports all kinds of operating platform, such as x86, Power PC, 68K, CPU32, SPARC, i960 and so on. The realization ways and programming method of serial communication between embedded VxWorks system of X86 operating s platform and PC was introduced.
