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

1. Serial Port Terminal (/dev/ttysn)The serial port terminal (serial port terminal) is a terminal device connected by a computer serial port. The computer regards each serial port as a character device. For some time, these serial port devices are usually called terminal devices, because at that time they were used to connect terminals. The device names corresponding to these serial ports are/dev/TTS/0 (or/dev/ttys0),/dev/TTS/1 (or/dev/ttys1), etc, the device numbers are (), (), and so on, respe

You typically use a hotkey alt+fn to switch between these virtual terminals. All of these TTY devices are matched by linux/drivers/char/console.c and vt.c.

They are not directly related to the actual physical device. If a program considers PTYP3 (master device) as a serial port device, its read/write operation on that port is reflected on the other TTYP3 (slave device) corresponding to the logical terminal. The TTYP3 is a logical device that another program uses for read and write
