Hi,
You have to use SerialPort Class which is part of Namespace:  System.IO.Ports.

Basically you use Serial port Write-line method to send an string to it.

For example for CR  use write method with "\r"
For LF  use write method with "\n"

For a example take a look here:

Thank you.
I'm using C# with System.IO.Ports.
The manual device, tells us that we need to send this sequence, but without citing the language.
[ENQ, 3, 0, CR, LF]

[enquiry, ID, CR, LF] // "3,0" is the ID of device "30"

I use the code below and works with others devices.
 private void timer1_Tick(object sender, EventArgs e)
        {
                string ID = "30";
                CommPort com = CommPort.Instance;
                ID = ConvertEscapeSequences(ID);
                com.Send(ID);
        }

Open in new window

Thanks in advance,
