[RC232] When a packet is transmitted from one module to another, what is the receiving module going to output on its UART? The exact number of bytes sent? Or will it add some extra information like “Byte count, sender address or CRC”?

The RC232 protocol is transparent: What you send in on one side , is what you get out on the other side. CRC is calculated, added, checked and removed by the module.
