Linux uses stty to display and modify terminal line settings

Sttty is a common command for changing and printing terminal settings under Linux.

1. Parameters:

1. Print terminal line settings

-a, --all Print all current settings in human-readable form; the -a parameter prints more detailed terminal information than the stty command alone.

-g, --save Print all current settings in a stty-readable format

-F, --file=DEVICE Open and use the specified device (DEVICE) instead of standard input (stdin)

--help show help and exit

--version display version and exit

2. Usage

1. stty size prints the number of rows and columns of the terminal

2. Disable lowercase output in the command line

stty olcuc #Open
stty -olcuc#Restore

3. Print the number of rows and columns of the terminal

stty size

4. Change the method of ctrl+D:

stty eof "string"

The system defaults to ctrl+D to indicate the end of the file, but this method can change it!

5. Shield display

stty -echo #Disable echo
stty echo #Open echo

Test Method:

stty -echo;read;stty echo;read

6. Ignore carriage return

stty igncr # enable
stty -igncr#Restore

7. Use it to set our serial port printing operation information.

stty -F /dev/ttyS0 speed 115200 cs8 -parenb -cstopb -echo

Explanation: Use stty to set the /dev/ttyS0 serial port, baud rate to 115200, data bit to cs8, parity bit to -parenb, stop bit to -cstopb, and -echo to disable terminal echo.
