Hello everyone, I have read the basic tutorial and googled about this topic, but I'm confused.
The context is: I'm sending simple characters from a microcontroller to a virtual terminal in my PC. The transmission protocol is RS232 (9600 baud, No parity, 8 bits, 1 stop bit) and I need to be able to capture the messages to later insert them into a database.
I have read something about a paid library but as I said I'm new to web programming.
Right now, I need to figure out how to detect an incoming character and save it.
