Have you check the specifications of the manufacturer? They should have information about it

I tried this code
byte b = byte.Parse(textBox1.Text);
serialPort1.Write(new byte[] {b }, 0, 1);
but now am getting hex value of 89..i need 89 itself

You can easily send a byte value by setting it into a variable as :

C#

private void button2_Click(object sender, EventArgs e)
{
    byte b = 89; // for a decimal value
    byte bh = 0x89; // for a hexadecimal value

    serialPort1.Write("r"+b); // not sure why the "r" is there
}

If the data from your textbox is not being parsed correctly then you should expalin what the error is.
