Yes, and how do I send and receive from Arduino to Arduino the same format, such that the content isn't misinterpreted. serial monitor only sends and receives ASCII. I guess I want to be able to develop code and test via serial monitor, but also want the contents to be interpreted by the other Arduino correctly.

The standard advice for newbies is to use ASCII format and follow this tutorial: https://forum.arduino.cc/t/serial-input-basics-updated/382007
