usually when you get garbage , it means that the speed on the serial port is incorrect.
what is the output of, the below command;
stty -F /dev/serial0
Can you also please make sure you are running the latest firmware as when the Pi 4 first came out, there was issues with the serial speed, which was later fixed.
