serial port - making call from gsm modem in C# -


I want to call GSM modem using C # I've written the following code, but I'm unable to call. Please tell me what the mistake is also tell me how to handle the response to the code from the modem so that I can display the message like "Call connecting" or "Can not connect". 

  Private Zero Button 1_Click (Object Sender, EventsErgus E) {Serial Port PO = New Serial Port (); Po.PortName = "COM3"; Po.BaudRate = int.Parse ("9600"); Po.DataBits = Convert toInt32 ("8"); Po.Parity = Parity.None; Po Port = stop One; Po.ReadTimeout = int.Parse ("300"); Po.WriteTimeout = int.Parse ("300"); Po.Encoding = Encoding.GetEncoding ("iso-8859-1"); Po.Open (); Po.DtrEnable = true; Po.RtsEnable = true; Po.DataReceived + = New SerialDataReceivedEventHandler (Port_DataReceived); Po.Write ("ATD9030665834;"); } Public Zero Port Data Reassembled (Object Sender, Serial Data ResourceAgent Eg E) {if (e.EventType == SerialData.Chars) {// What is the response to write here? }}    
 
 
 Use the port. Wrightite ("ATD" + phno + ";");  
 This will definitely solve your problem ..  
 Use the port to use the feedback. Compare to readxing () and your requirement as if it is easy :)  
 Good luck ..

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
