The primary function of Sscom is deceptively simple: it sends and receives data through a COM port. Yet, this simplicity belies its profound necessity. When a developer uploads code to an Arduino or an ESP32, they are essentially flashing a brain. But once the brain is awake, how does one speak to it? Sscom provides the raw, unfiltered line of communication. It is the interpreter that translates the cryptic language of UART (Universal Asynchronous Receiver-Transmitter) into readable text on a screen.
