You could try something like this....C# Win32 application

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.IO.Ports;

namespace WindowsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            SerialPort sp = new SerialPort();
            sp.PortName = "COM10";
            sp.BaudRate = 9600;
            sp.Parity = Parity.None;
            sp.DataBits = 8;
            sp.StopBits = StopBits.One;
            sp.Handshake = Handshake.XOnXOff;
            sp.DtrEnable = true;
            sp.RtsEnable = true;


            sp.Open();

            if (!sp.IsOpen)
            {
                MessageBox.Show("Serial port is not opened");
                return;
            }

            sp.WriteLine("AT" + Environment.NewLine);
            sp.WriteLine("ATD=\"" + "Destination Number;" + "\"" + Environment.NewLine);

        }
    }
}
