Hi friends!
Now I try to find a code for displaying a text box text into a pole display. I have tried some codes and I have gone through lots of websites, but I couldn't be able to find the way.
First of all I want to know whether is it possible or not? If possible how to do that?
I tried like the below link and the below simple code for the button click.

private void button1_Click(object sender, EventArgs e)
{
SerialPort sp = new SerialPort("COM5", 9600, Parity.None, 8, StopBits.One);
sp.Open();
// to clear the display
sp.Write(Convert.ToString((char)12));
// first line goes here
sp.WriteLine("Total : " + textBox1.Text + " RM");
sp.Close();
sp.Dispose();
sp = null;
}
The below error is displaying
The port 'COM5' does not exist.
When I plugged the pole display it hasn't detect under "PORTS (COM & LPT)". It has been detected under "Human Interface Devices"
I have to pass whatever text typed inside the text box to the pole display.

I followed the above link to configure the pole display. In this link they are suggest something called Virtual Com Port Driver. I've downloaded a driver from the below link,
http://www.ftdichip.com/Drivers/VCP.htm
I installed the driver, after installation it doesn't prompt for anything.
Can anyone suggest me the way to use the Virtual COM Port Driver
Thanks in advance.
