You say you "have tried with lot of articles" but you do not say anything about any kind of a problem.

For what? For serial communications? Must be tons of examples out there everywhere for you to look at. "non of them were helpful" does not tell us anything about your problem.

So what method/server type does the device provide to transfer files to it? It sounds like you're doing a lot of guessing and work without knowing anything about what the device expects.

its a Processor: ARM9 32-bit Core CPU and OS:LINUX Operating System (Ver 2.6) and Regarding Ports am trying to Use peripheral port RS-232. if any thing am missing just let me know. so that it can help me to transfer a text file to that particular Device.

Ok, that's the device hardware. What server on the device is listening to the serial port and what protocol does it speak? If you jUst start sending bytes how is the server going to know what to do with it?

Maybe the MSDN docu is a start: http://msdn.microsoft.com/de-de/library/system.io.ports.serialport(v=vs.110).aspx[^]

If you get the example working for your device(s), chances are high you manage to transfer a file too...

You did not clarify what your embedded device is. But you can find the Kermit source files here: www.kermitproject.org[^]

I do not however, have the time to step you through how to implement Kermit. If you are looking for a complete solution you need to spend time and read the webistes information. When you learn how to use the libraies you wil have gained some valuable experience and added new tools to your skillset.

Good luck.

this is what helped at end

C#

public delegate uint KERMITPROC(HANDLE WPARAM, HANDLE LPARAM);

[DllImport("kermitlib.dll", EntryPoint = "SendFile", SetLastError = true)]
private static extern int SendFile(string strFileName, HANDLE hDevice, KERMITPROC KermitProc);

public static uint KermitProc(HANDLE wp, HANDLE lp)
{
    string buff = "";
    double per = 0;
    switch (wp.ToString())
    {
        case "S": // Send Initiation
            myprintf(0, 1, "Sending S Packet ...");
            break;
        case "F": // File Header packet
            myprintf(0, 1, "Sending F Packet ...");
            break;
        case "A": // File Atrribute packet
            myprintf(0, 1, "Sending A Packet ...");
            break;
        case "D": // Data Packet
            per = (double)((Convert.ToInt16(lp) * 100) / filelength);
            buff = string.Format("File sending - {0:f0}{1}", per, Convert.ToChar(37));
            myprintf(0, 3, buff);
            break;
