I am trying to send sms via D-Link GSM modem. I am new on this. My code shows Unable to setup COM port I did not add any additional file, library or any modification in php.ini file in xampp. just installed software provided by modem. My operating system is windows 10. I am mentioning my code, though I got it from internet.
$mobile_number=$_POST['mobile_number'];

It's Look like You are using a D-Link USB GSM Modem.
in this case Modem COM port doesn't show in Device Manager Automatically.
First you must start D-Link Connection Manager SoftWare and then you can find your modem under MODEM category in Device Manager.
R-Click on it and Open Properties window.
You can find COM port on it!

My problem is when I try to connect the Android application with Java socket identified by an IP and a port 4444 with a PHP service, identified by the same port, and keep this connection open to accept multiple connections via the Android app.
So with a second Android device if we connect to PHP we will have the same communication channel as the one device and we cannot identify which device is connected via PHP.
Is there a possibility to differentiate these two connections via the PHP file or instantiate two different PHP service for the two devices.
The Android code:
public String connect() {
Socket socket = null;
try {
socket = new Socket();
// This limits the time allowed to establish a connection in the case
// that the connection is refused or server doesn't exist.
socket.connect(new InetSocketAddress(dstAddress, dstPort), context.getResources().getInteger(R.integer.time_out));
// This stops the request from dragging on after connection succeeds.
socket.setSoTimeout(context.getResources().getInteger(R.integer.time_out));
// socket = new Socket();
// socket.connect(new InetSocketAddress(dstAddress, dstPort), 2000);
if (!socket.isConnected())
throw new SocketException("Could not connect to Socket");
DataInputStream DIStream = new DataInputStream(socket.getInputStream());
DataOutputStream DOStream = new DataOutputStream(socket.getOutputStream());
DOStream.write(numCmd.getBytes(), 0, numCmd.getBytes().length);
DOStream.flush();
response = DIStream.readLine();
DOStream.close();
DIStream.close();
socket.close();
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
response = "{\"Error_no\":5000}";
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
response = "{\"Error_no\":5000}";
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
response = "{\"Error_no\":5000}";
} finally {
if (socket != null) {
try {
socket.close();
if(response == null){
response = "{\"Error_no\":5000}";
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
response = "{\"Error_no\":5000}";
}
}
}
// Log.i("resp",response);
return response;
}

You can run a separate server process for each client. Each server process needs to have an unique IP address or TCP port. Each client needs to be configured to connect to the correct server address and port. This is difficult to manage and doesn't scale.
At the server side, you can get the peer address, that is the IP address and port of the client. In PHP, you can use socket_getpeername() for this. However, depending on the network setup, this might not be the IP address of the client itself. It can be the IP address of an intermediate gateway or other network device. Also, the client IP address might be dynamic.
The best solution is to send some identification from the client to the server when the clients connects to the server. This can be a name or some other unique identification. You have to change the protocol between the client and server to support this. The client needs to know when and how to send the identification. The server needs to know when and how to receive the identification.

After Debug above Code I found that when i first time connect my device and run it php executing this line as like as infinity loop and before this line all debugmsg and other code running fine please help me
$buffer = fread($this->fp, 8192);
I m writing a websocket based client server in PHP.Server is listeninig for clients which get connected from a browser, when client write something its echoed
back to the client. Client input and new connection from the client are monitored by using stream select.
In my previous work I used stream select to get output of the C program and display it on the browser now I want that when a client
send some message I execute a C program using proc open. C program outputs "hello" message in a loop after certain time, I want that when ever there
is output on the C program I send it to the client browser.
Client browser successful gets connected, when client sends data the server echo it back, the C program gets executed on server but I cant monitor its STDOUT by using same stream select that is monitoring my sockets.
I am not able to monitor my child process STDOUT using stream select. By using select How can I monitor the new process STDOUT that I started using proc open
,It looks that some how I lost the STDOUT descriptor that is usually accessible after starting the C program by using proc open.

Thankyou
i was saving the stdout in read_sock instead of read_socks array, now its resolved

Try this below code hope it helps,
Note : uses php_serial.class.php
Code :
<?php
require("php_serial.class.php");
$serial = new phpSerial;
// First we must specify the device. This works on both linux and windows (if
// your linux serial device is /dev/ttyS0 for COM1, etc)
$serial->deviceSet("/dev/ttyS0");
// We can change the baud rate, parity, length, stop bits, flow control
$serial->confBaudRate(9600);
$serial->confParity("none");
$serial->confCharacterLength(8);
$serial->confStopBits(1);
$serial->confFlowControl("none");
// Then we need to open it
$serial->deviceOpen();
// To write into
$serial->sendMessage("AT+CMGF=1\n\r");
$serial->sendMessage("AT+cmgs=\"+912709345x23\"\n\r");
$serial->sendMessage("Hi, This is the sms that I sent to you using PHP script with serial Port communication with my phone as serial device!! GN - VKSALIAN \n\r");
$serial->sendMessage(chr(26));
//wait for modem to send message
sleep(7);
// Or to read from
$read = $serial->readPort();
echo $read;
// If you want to change the configuration, the device must be closed
$serial->deviceClose();

I would like to send SMS from my GSM modem. I tried to implement this using this link as reference. But my modem will not produce any response.Any help..Thanks in advance....
Here is my code snippet..
$gsm_send_sms = new gsm_send_sms();
$gsm_send_sms->init();
$status = $gsm_send_sms->my_send_message_function("+09524566775", "raja");
$gsm_send_sms->close();
//Send SMS via serial SMS modem
class gsm_send_sms {
public $port = 'COM7';
public $baud = "9600";
public $debug = true;
private $fp;
private $buffer;
//Setup COM port
public function init() {
$this->debugmsg("Setting up port: \"{$this->port} # \"{$this->baud}\" baud");
exec("MODE {$this->port}: BAUD={$this->baud} PARITY=N DATA=8 STOP=1", $output, $retval);
if ($retval != 0) {
throw new Exception('Unable to setup COM port, check it is correct');
}
$this->debugmsg(implode("\n", $output));
$this->debugmsg("Opening port");
//Open COM port
$this->fp = fopen($this->port . ':', 'r+');
//Check port opened
if (!$this->fp) {
throw new Exception("Unable to open port \"{$this->port}\"");
}
$this->debugmsg("Port opened");
$this->debugmsg("Checking for responce from modem");
//Check modem connected
fputs($this->fp, "AT\r");
//Wait for ok
$status = $this->wait_reply("OK\r\n", 5);
if (!$status) {
throw new Exception('Did not receive responce from modem');
