Q. I'm trying to write a string of characters to the serial port, which is successful, However as soon as i try and read back what has been sent, it only reads half of the the data initially sent. can anybody please help? Do i need some sort of a delay when reading or sending?

Code:

serialPort1.Open();
serialPort1.Write("Communications Solutions");


recieved_data = serialPort1.ReadExisting();

textBox1.Text = recieved_data;

serialPort1.Close();

// Recieved_data only displays half the characters in the text box.
