The screen command is a terminal multiplexer that allows you to run multiple terminal sessions within a single terminal window. It does not have the capability to set the baud rate for terminal communication.
The baud rate is a measurement of the speed at which data is transmitted over a serial communication link. It is usually specified in bits per second (bps). The standard baud rates for serial communication are 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200 bps.
To set the baud rate for a serial communication link, you need to use a terminal emulation program that supports serial connections, such as minicom, picocom, or screen, and configure it to use the desired baud rate.
For example, in screen, you can connect to a serial port with a specific baud rate using the following syntax:
screen /dev/ttyS0 115200
In this example, /dev/ttyS0 is the device file for the first serial port, and 115200 is the baud rate.
It’s important to note that both the device and the baud rate must match the settings of the device you are communicating with in order to establish a successful connection.
