Usage
=====
Install using npm:

npm install --save gsm-modem

Require the module:

var Modem = require('gsm-modem');

Connect to the modem:

var modem1 = new Modem({
ports : ['/dev/ttyUSB0', '/dev/ttyUSB1', '/dev/ttyUSB2']
});
modem1.connect(function (err) {
if (err) {
console.error('Error connecting modem: ', err);
return;
}
// Start giving commands here...
}

Connect options
---------------
__ports__: Array of serial ports to search for a modem. The module will try to connect to every ports specified and send _AT_ command. The first port modem answers to will be used as data/command port, others will be used for listening only. _Default: [/dev/ttyUSB0,/dev/ttyUSB1,/dev/ttyUSB2]_

__debug__: boolean if the module should output all data it sends/receives. _Default: false_

__auto_hangup__: boolean indicating whether modem should send _ATH (hangup)_ command when incoming call is received. _Default: false_

__commandTimeout__: milliseconds, how long to wait for response on any AT command. _Default: 15000_

__ussdTimeout__: milliseconds, how long to wait for USSD after sending the command. _Default: 15000_

__forever__: boolean, indicated whether module should run in daemon mode automatically handling modem connects and disconnects. _Default: false_
