设备驱动中主要要设计的数据结构是设备结构体，按键的设备结构体中应包含一个缓冲区，因为多次按键可能无法被及时处理，可以用该缓冲区缓存按键。此外，在按键设备结构体中，包含按键状态标志和一个实现过程中要借助的等待队列、cdev结构体。为了实现软件延时，定时器也是必要的

串口通讯实验.在Linux操作系统中对底层终端的处理是一个非常复杂的过程，需要处理许多不同类型的设备（包括调制解调器、终端仿真、伪终端等）。Linux 系统处理终端的方法是通过串行接口连接的控制台与系统通信并运行程序。由于越来越多的厂商都参与终端的生产，而且每个厂商都是为自己的终端设计自己的命令集，所以需要有一种方法对终端的访问进行一般化处理。Linux系统使用一个能力数据库terminfo 来描述每个终端的能力以及调用这些功能的方法。
Serial communication experiments. In the Linux operating system on the bottom end of the treatment is a very complex process, need to deal with many different types of equipment (including modems, terminal emulation, pseudo-terminals, etc.). Linux system processing terminal is connected through a serial interface, communication with the system console and run the program. As more and more vendors are involved in the production of the terminal, and each vendor is for their own terminal design their own command set, so the need for a way to generalize to the end of the visit was handled. Linux systems use a terminfo capability database to describe the capacity of each terminal as well as the method call these functions. (2010-02-09, Unix_Linux, 1209KB, 下载7次)
