这是与GSM 900调制解调器建立连接的代码...，代码可完美。但是，当我尝试使我的手机（Micromax Doodle A111-works完美地适合所有命令中的命令）代替GSM 900调制解调器。.它说没有电话连接。为了连接手机，我必须做什么变化。

和该代码必须在连接后接收MSG并在屏幕上显示并在TEH消息中访问内容。

我认为您应该先添加ComboBox，并使用此代码自动检查所有可用端口：
private void comboBox1_DropDown(object sender, EventArgs e)
{
comboBox1.Items.Clear();
try
{
#region Display all available COM Ports
string[] ports = SerialPort.GetPortNames();
// Add all port names to the combo box:
foreach (string port in ports)
{
this.comboBox1.Items.Add(port);
}
#endregion
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
，您会看到问题所在。谢谢。
