The screen command is a utility for creating and managing terminal sessions in Unix. It does not have a built-in option for setting the baud rate for terminal communication.
However, you can use the stty command to set the baud rate of the terminal device. For example, to set the baud rate to 9600, you can use the following command:
stty 9600
This will set the baud rate of the terminal device to 9600.
Note that the stty command only affects the terminal device itself, and not the screen session. If you want to set the baud rate for a screen session, you will need to run the stty command within the screen session.
For example, you can start a screen session and set the baud rate to 9600 using the following commands:
screen stty 9600
This will start a new screen session and set the baud rate of the terminal device to 9600.
Overall, the stty command is a useful tool for setting the baud rate of the terminal device, and can be used in conjunction with the screen command to set the baud rate for screen sessions.
