'C' instruction to send multi-byte command

I have an Arduino related question. What is the ‘C’ language instruction to send a multi-byte command from an Arduino GPIO port to a device? Thank you in advance for your assistance.
Hello,
In Arduino or most of the MCU like Arduino, they use the Serial output pin to transfer multi-byte data.
You could refer to the official docs for Arduino to get to know about the Serial output.
https://www.arduino.cc/reference/en/language/functions/communication/serial/print/
It's Serial.print()
And if you feel the Hardware Serial is not enough for you, cuz you want to connect more than one Serial Sensor.
The Arduino provides a software Serial library, you could init some of the GPIO(Not all of them) as your SoftSerial.
You could also refer to the SoftwareSerial Doc for detail:
https://docs.arduino.cc/learn/built-in-libraries/software-serial
They have also provide a sample code for it.
