GSM module is not working

[vishvas-prajapati]

var device = '/dev/ttyUSB0';
var message = {
text : 'Hello',
receiver: '+91xxxx',
encoding: '7bit'
};

modem.open(device, function(){
console.log('OPEN!!');
});

/*

• Send SMS
  */
  modem.sms(message, function(err, res){
  console.log('SMS', err, res);
  });

OUTPUT:

node gsm_modem.js
OPEN!!

It can't send sms. 'delivery' method is also not working.

After opening the modem, you have to call the sms function.

modem.open(device, function(){
modem.sms(message, callback);
});

[vishvas-prajapati]

var modem = require('modem').Modem();
/*

• Variables
  */
  var device = "/dev/ttyUSB0";
  var message = {
  text : "Hello",
  receiver: "+91xxxxxxxxxx",
  encoding: "7bit"
  };

/*

• Connection String
  */
  modem.open(device, function(){
  console.log('OPEN!!');

  /*

  • Send SMS
    */
    modem.sms(message, function(err, res){
    console.log('SMS', err, res);
    });

  /*

  • Delivery SMS
    */
    modem.on('delivery', function(res){
    console.log('Delivery', res);
    });

  modem.on('ring', function(res){
  console.log(res);
  });
  });

Output:
node gsm_modem.js
OPEN!!

But Methods are not working. can you please help me here?
Should I do any configure at other? Send sms is working in minicom terminal.

I have the exact same problem.
I have a GSM900 modem connected through an Arduino.
The Arduino only forwards the serial port to and from the GSM900 to my computer via USB serial.
I am able to communicate with the modem using minicom, and the npm package "serialport".
However, using "modem", it doesn't work.

var util = require("util");
var modem = require('modem').Modem();

var device = '/dev/ttyACM0';

modem.open(device, function(){
          util.log("Modem ready");
          var msg = {
                    text: "test",
                    receiver: "00000000",
                    encoding: "7bit"
          };

          modem.sms(msg, function(err, references){
                    util.log(err);
                    util.log(references);
          });
)

The "open" callback seems to work, I get the "Modem ready" message logged, but the "sms" callback never fires, no error or anything.

Have you guys tried other ports?
Some modems open up 3 different ports and only one of them responds to events.

For example my modem opens up /dev/ttyUSB0, /dev/ttyUSB1 and /dev/ttyUSB2 and only one of them works (/dev/ttyUSB2 in my case)

This may sound dumb but my modem is what huawei call a wifi wingle that connects to 4G and serves wifi to provide internet access. it has an sms function which as far as I can tell is only available by loading the config page in my browser.

What Id like to know is can I use this package to connect to my modem?
if so what would the device string look like?
