Hello everybody,
I have been working with C#, specifically PortSerial, so I've already read a
lot about that in MSDN Forum.
In a nutshell, I have a *client* that will dial a number and make a request,
whereas the *server* will response. The client dials, requests and
everything works pretty fine, whereas the server answer the call, but the
issue is just that doesn't receive the request! I am sure about that because
the instruction "MessageBox.Show("Received: " + received);", received =
"req", is never called, I mean the Message.ShowBox never shows "Received:
req";
Remark: I've been testing both application using two computers and phone
lines, so that a computer is the server whereas the other one is the client.
I've already spent much time working on it and until now I wasn't
successful.
Thanks in advance.
###Client###
this.serial = new SerialPort();
this.serial.DtrEnable = true;
this.serial.DataReceived += new
SerialDataReceivedEventHandler(this.port_DataReceived);
private void port_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
string received = serial.ReadExisting();
Thread.Sleep(5000);
MessageBox.Show("Message Received: " + received);
}
//Dial Method
private void button1_Click(object sender, EventArgs e)
{
string number = textBox1.Text;
if (!serial.IsOpen)
serial.Open();
serial.Write("ATDT" + number + ";\r\n");
Thread.Sleep(5000);
}
//Request Method
private void button2_Click_1(object sender, EventArgs e)
{
serial.WriteLine("req\r\n");
Thread.Sleep(5000);
MessageBox.Show("Message Requested");
}

###Server###

switch (received) {

Thread.Sleep(5000);
MessageBox.Show("Answered");
break;

MessageBox.Show("Request Received");
this.serial.WriteLine("Oi\r\n");
