So I want to check whether my Matlab code which I made for serial communication through the device does the desired job. So I need a method to test serial communication via any of the COM ports without connecting a serial com device to the PC. Is there any such method that I can Tx Rx serial data from Matlab to COM ports?

This example describes the steps you use to perform any serial port task from beginning to end.
The serial port session comprises all the steps you are likely to take when communicating with a device connected to a serial port. These steps are:
![]()
The serial port session is reinforced in many of the serial port documentation examples. To see a basic example that uses the steps shown above, see Query a Serial Port Device.
