how to set the flow control of serial port?
<p>I  have a <code>SerialPort</code> with a setup with flow control to be 1. How to set it in c#. 
I have newline <code>char</code> in my port setup and I assume that different to the flow control. My port setup so far is as below. Can anyone help me with setting the flow control please ? Thank you.</p>

<pre><code>SerialPort _comm = new SerialPort
{
    PortName = string.Concat("COM", comPort),
    BaudRate = 9600,
    Parity = Parity.None,
    DataBits = 8,
    StopBits = StopBits.One,
    ReadTimeout = 1000,
    WriteTimeout = 5000,
    NewLine = "\r"
};
