As an embedded product, the company uses the ARM kernel and Linux operating system (not uClinux ). My recent work is to mount a previously prepared module (via serial port for communication) to the system, and control a series of work of this module through serial port, and require Into a separate driver (not controlled by an application ). I also want to familiarize myself with the development method of the device driver in Linux. The Development Board of another company we bought, Linux, can n

This article was reprinted from: http://ju.outofmemory.cn/entry/2811681. ObjectiveBecause of the serial port, TTY is the most common type of equipment in Linux, and a little bit about the students of Linux system is not unfamiliar to it. Nevertheless, it is believed that few people can return to the question: what is a TTY? What do we mean by the concept of terminal (terminal), console, etc. that we often h

CentOS starts 6 TTY by default. in the console, you can use the Alt + [F1 mdash; F6] key to switch between different terminals, using SSH virtual terminal to manage remote servers is not available, which can reduce the number of TTY started to reduce system resource usage. CentOS5 modify the description of the configuration file to prohibit start of TTY: 123456c

, enabling multiple users to log in at the same time, including logging on at the same time. The console "Alt" + "Fx" is capable of switching to the X (character dummy) terminal. If you need to jump from X-window to the first (character dumb) terminal, you need "Ctrl" + "Alt" + "Fx". In general, if you want to return Xwindow from the console, "" Alt "+7" can be returned to the Xwind graphical interface. (The Linux distribution provides 7 virtual screens, the 1~6 is the console terminal ((charact

Article title: Basic Knowledge: Linux Terminal tty device driver. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. In Linux, terminal devices are very important. without terminal devices, the system will not be able to provide feedback to users. Linux contains three types of terminal devices: Console, serial port, a

For some understanding and doubts about TTY, please give us some advice-general Linux technology-Linux programming and kernel information. The following is a detailed description. Brother, I am developing some gadgets under VxWorks. Although I have been developing on this system before, I did some upper-layer applications at that time, since the company platform encapsulates the interface of the operating system, it does not care about how to implemen
