Serial communication is the process of sending data sequentially one bit at a time, over a communication channel or computer bus [5,6,7]. RS-232 is a standard for serial binary data transfer between a data terminal equipment (DTE) and a data circuit-terminating equipment (DCE), commonly used in computer serial ports. | 526: Invalid SSL certificate

I use the modbus tester software from Eltima All data going through the serial port I see in my logs.
