  1. i tried programatically i got this code

    imports System.IO.Ports

Private Shared Sub SendSampleData()
 ' Instantiate the communications
 ' port with some basic settings
 Dim port As New SerialPort("COM1", 9600, Parity.None, 8, StopBits.One)

 ' Open the port for communications
 port.Open()

 ' Write a string
 port.Write("Hello World")

 ' Write a set of bytes
 port.Write(New Byte() {&Ha, &He2, &Hff}, 0, 3)

 ' Close the port
 port.Close()
End Sub

If Device Manager says that your computer doesn't have any serial ports then you need to make sure that your system can detect the serial ports in the first place.

...assuming your computer has a serial port. Does it?

If it does (and I assume it does) then it's probably disabled in BIOS. You need to go into your computer's BIOS or EFI firmware at startup and enable the serial ports.

Also, never hardcode the serial port name in your code, e.g. "COM1", instead use SerialPort.GetPortNames() to get a list of available ports on your computer and let your users choose from the list.
