Is it possible to use a serial port like session in c#?
- by Pandiya Chendur
I am using serial port communication in my asp.net webform application...
private bool sendSMS(int portNo, string mobNo, string details)
{
try
{
SerialPort SerialPort1 = new SerialPort();
SerialPort1.PortName = "COM" + portNo.ToString();
SerialPort1.BaudRate = 9600;
SerialPort1.Parity = Parity.None;
SerialPort1.DataBits = 8;
SerialPort1.StopBits = StopBits.One;
SerialPort1.RtsEnable = true;
SerialPort1.DtrEnable = true;
SerialPort1.Encoding.GetEncoder();
SerialPort1.ReceivedBytesThreshold = 1;
SerialPort1.NewLine = Environment.NewLine;
SerialPort1.Open();
SerialPort1.Write("AT" + SerialPort1.NewLine);
Sleep(500);
SerialPort1.Write("AT+CMGF=1" + SerialPort1.NewLine);
Sleep(500);
SerialPort1.Write("AT+CMGS=" + (char)34 + mobNo + (char)34 +
SerialPort1.NewLine);
Sleep(1000);
SerialPort1.Write(details + (char)26);
Sleep(2000);
SerialPort1.Close();
}
catch
{
}
return true;
}
This method works when i send i single message... But when want to send sms in bulk opening and closing port everytime is not a good idea... So my question is it possible to use a serial port like session in c#?... When i open a port i want it to be open for 1 hour and then if my time expires i want to close the port and open it the next time... Any suggestion...
