hi
i am doing a project in vb.net on serial communication.
The command i write in text box is written on serial port and responds accordingly and displays the result in multiple text box along with the command. I want to display only result but not command.i want to delete command from the result.
i am using RxString = SerialPort1.ReadExisting because of which what ever is present on serial port is getting displayed.I dont want command written to serial port to be displayed.
can ayone please tell me a solution for this.
