Serial Port Data Communicatio

Question

Hi I want to display updated data from the same serial port to four different forms at same time to plot online graph to these four windows ,I wrote the code for single window as follow

private void serialPort1_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)

{

string s = serialPort1.ReadExisting();

get1 = s.ToCharArray();

System.IO.StreamWriter file3 = new System.IO.StreamWriter("d:\\" + MTIME1.Text + ".csv", true);

file3.Write(s);

file3.Close();

for (int i = 0; i < s.Length; i++)

{

gets[0] = get1[i];

if (flag != 0)

{

switch (gets[0])

{

case space:

count1 = 0;

count++;

break;

case enter:

for (int l = 0; l < 10; l++)

{

m[l] = (c[0, l]);

}

s1 = new string(m);

for (int l = 0; l < 10; l++)

{

m[l] = (c[1, l]);

}

s2 = new string(m);

for (int l = 0; l < 10; l++)

{

m[l] = (c[2, l]);

}

s3 = new string(m);

for (int l = 0; l < 10; l++)

{

m[l] = (c[3, l]);

}

s4 = new string(m);

for (int h = 0; h < 20; h++)

{

for (int z = 0; z < 20; z++)

{

c[h, z] = Convert.ToChar(0);

}

}

d1 = Convert.ToDecimal(s1);

How I can do this? Please Help me
