gsm-modem v0.3.19
node-gsm-modem
NodeJS module to control GSM modem connected to serial port.
Thanks to
Emil Sedgh for PDU.js. I had to change it though.
Chris Williams for node-serialport
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...
}
