Communicatng with arduino over serial port

I am using screen to communicate with arduino over serial port, i start screen like this:

screen /dev/ttyACM0 115200

then I try to send a command but every key I press on the keyboard get sent straight away, how to make it enter until I press
Enter

key before sending input to arduino?

You need to tell us what "screen" is and post a link to its user manual.

I hope the OP takes the trouble to thank you for doing his work for him.

I do believe it would have been more instructive for the OP if you had left it to him to answer the question.
