基于linux操作系统的多串口驱动研究

THE RESEARCH OF MULTI-SERIAL DRIVE BASED ON THE LINUX OPERATING SYSTEM

在介绍基于linux操作系统的多串口驱动设计理论基础上,重点研究对多串口编程的技术,实现基于tty的核心设计,可作为实现串口终端设备集中管理、实时数据采集的服务器主板应用。其特点是可以采用ARM平台,但完全兼容X86平台,用户原来在X86平台下编写linux操作系统的多串口驱动的程序只需做一次重新编译即可实现移植,达到基于Linux操作系统的多串口驱动实时通讯的目的。

We introduce the Linux operating system based on the design theory of multi-serial port drive and realize the core design based on tty with the multi-serial port programming technology,which can be used as a serial port terminal equipment to realize the centralized management,the real-time data acquisition server application motherboard.Its characteristic is can be used with ARM platform,but is fully compatible with X86 platform.Furthermore,the original X86 operating system Linux multi-serial port drive program in the workbench need only recompile to realize the transplant,which is based on Linux operating system to the serial driver real-time communication.
