The command "stty" is used to change or display terminal line settings in Unix-like operating systems. It stands for "set terminal teletypewriter".
In this specific command, "--file" option is used to specify the file or device that you want to configure. The "${path-to-device_file}" is a placeholder that should be replaced with the actual path to the device file you want to modify.
The "speed" parameter is used to set the baud rate of the specified device file. Baud rate refers to the number of signal units transmitted per second. It determines how fast data can be sent or received over a serial connection.
