在ARM9等开发板上调试GSM等串口模块的工具，实现最基本的minicom功能，程序本身会为每条命令加上\r，如果不需要，请自己修改程序，无退格功能。-ARM9 development board such as in GSM and other debugging tools for serial modules, minicom to achieve the most basic functions, the process itself for each command with \ r,

at91sam9261s uart 开发板自带程序-at91sam9261s uart

Revised by Kenneth Albanowski for m68knommu. Basic problem: unaligned access kills, so most of the assembly has to go.

linux环境下的串口源码，经过调试，可以使用，基本实现了异步收发的功能。-linux environment serial source, after debugging, you can use the basic realization of the UART functions.
