Linux 操作系统提供进程间通信（IPC）机制，用来保证正在执行的进程在内核的协调下能够 共享资源、同步以及交换数据等。Linux 支持大量进程间通信机制，包括信号、等待队列、管道 以及Unix 系统V 中提供的进程间通信机制，如消息队列、信号量和共享内存。-Linux operating system to provide inter-process communication (IPC) mechanism used to ensure that the process is being implemented in coordination with the core to share resources, synchronization and exchange information. Linux support a large number of inter-process communication mechanisms, including signal and wait for the queue, pipeline and the Unix System V to provide inter-process communication mechanisms, such as message queue, the signal volume and shared memory.

COBS-consistent overhead byte stuffing，一种串行通信字节流packetize的算法，在PPP和HDLC串行通信中均有用，笔者把它用在单片机串行通信程序中，非常成功。包中的两个工程阐释了算法原理。pdf文档进一步作了说明。-COBS-consistent overhead byte stuffing, a serial communication byte stream packetize algorithms, in the PPP and HDLC serial communications are used, the author put it in single-chip serial communication program, very successful. Package the two projects to explain the principle of the algorithm. pdf document for further clarification.
