UART to Ethernet with Raspberry Pi
You can control your Raspberry Pi using the general-purpose input/output (GPIO) digital signal pin on the integrated circuit board or use the serial console to access the kernel boot messages with UART. You can also connect and interface with other devices like Arduino, ESP8266 etc.
In order to connect your Raspberry Pi to UART, you need to enable UART connection and connect your RPi to UART Bridge. A UART bridge translates the data that is sent and received between different devices.
Open the Computer Management function on your computer. Connect your UART Bridge with the relevant COM/LPT ports. A driver for the virtual COM port may be required.
By using Putty or another Terminal app, you can configure your serial connection and determine basic settings like baud rate, parity, stop bits etc. Enable logging and specify the log file name and location. All session output will be saved to this log file.
