We need to include two namespaces in order to use the Serial. Port class: using System. IO. Ports; using System. IO; We now need to instantiate a Serial. Port object. There are several constructors to choose from to specify different frame formats but in general the easiest to use is the following: Serial. Port(string port. Name, int baud. Rate)An example of this would be: Serial. Port my. Serial. Port = new Serial. Port( “COM3”, 9. 60. Here I am using COM3 at 9. You can find the full list of constructors in the link in the intro. Now that we have created our Serial. Port object, we need to open the port using the Open() method. When we are done we will want to close it using the Close() method: my. Serial. Port. Open(); my. Serial. Port. Close(); Several notes: when you use any operation that uses a serial port there is a good chance that an error will occur. For this reason we want to write our code for the serial port within a try – catch block. This will prevent our program from crashing if, for example we tried to open a port that didn’t exist. It is not necessary to instantiate our object within the try – catch block, but we want to open, close, read, and write within it.//this simply creates a Serial. Port object then opens and closes the port. Serial. Port my. Serial. Port = new Serial. Port( “COM3”, 9. 60. In the next step we will introduce how to read from a serial port.
