Here is the logical sequence of events:

1: A new SmS is received and processed by Method "CommandHandler(string[] smsText)", this method decodes the sms and calls a specific method based on the switch structure Value.

2: case "monitor": calls RemoteScan(parameters[2]);

3: RemoteScan calls RemoteMonitor() inside ReaderMonitor Form.

4: RemoteMonitor() calls ComPortSetup() which opens the com port.

5: RemoteMonitor() must then display the Form and return true or false back to RemoteScan inside SmsProcessor.

6: CommandHandler() will then call SendResponse();

Hi, Bill I really do appreciate you taking precious time out of your busy schedule to lend a helping hand. Kindly allow me to post a drop box link with the complete code of two classes in question.

As it stands, RemoteMonitor() is called inside a switch structure, at the end of the Method() that implements the switch structure that is where the SMS sending Method() is.

Yes the form does not show in Task manager and must be on top other forms. I wish I could send you the whole code but it is too big. I unless you don't mind.

I have changed the code according to the sample you provided. but now I can't send sms back to the sender. The code locks all threads until the form is closed.

Removing method RemoteMonitor is causing errors because the method is using controls of ItemMonitor Form??

Sorry to respond this late: I was trying something you guys mentioned about threads. I did something like this:
public bool RemoteMonitor()
{
this.Invoke(new ClearOutPutBoxEvent(ClearOutPutBox));

isStartButtonClicked = true;

object isOpen = null;

isOpen = this.Invoke(new RemoteScanEvent(ComPortSetup));

thread.Start();

return Convert.ToBoolean(isOpen);
}

public void WorkThreadFunction()
{
try
{
//this.Invoke(new Action(() => this.Show()));
this.ShowDialog();
}
catch
{
// log errors
}
}

however the code returns but does not display the form anymore.

okay, let me give it a try, thank you

If RemoteMonitor() returns false, it means that the "isOpen = this.Invoke(new RemoteScanEvent(ComPortSetup));" a call to ComPortSetup() which opens up a serail port to talk to RFID hardware was not successful, I will have to dispose the form and send sms message.

okay, thnk you

kindly pardon me but I'm not sure how to check for that.

I have registered the event.
scanningPort.PinChanged += scanningPort_PinChanged;
