Controlling DTR and RTS pins of Serial Port using Win32 API and C/C++

In the previous tutorial we learned about communicating with the serial port (reading and writing) using Win 32 API. 

In this tutorial,

we will look into another function that will let us control two more pins, RTS and DTR

Unlike RXD and TXD pins that are used for sending and receiving data, 

Build your own Data Acquisition and Logging System to CSV file using Python and Arduino

python serial port data logging with timestamp to csv on windows and linux

In this tutorial,We will build a low cost multi channel data acquisition and logging system using Python & Arduino UNO board that will log and save data to  a CSV (Comma Separated Values) text file on the disk.
