Raw-Modem

A library to allow sending raw command to a modem and retrieve the response in text format.

This library was created because sms-device module needs another driver beside gammu to control the modem but anyone can use this module as it is.

Installation

npm install raw-modem

Usage

Using in code

import {RawModem} from 'raw-modem';
 
let modem = new RawModem();
 
//Send sms using Wavecom modem
modem.open({
    baudRate: 115200
})
.flatMap(() => modem.send('AT+CMGF=1\r'))
.flatMap(() => modem.send('AT+CSMP=1,173,0,7\r))
.flatMap(() => modem.send('AT+CMGS="[phone]"\r', (buffer:any, subscriber: Rx.Subscriber<string>)=>{
                            console.log('cmgs response:', buffer.toString());
 
                            let responseString = buffer.toString().trim();
                            if(responseString === ">"){
                                subscriber.next("");
                                subscriber.complete();
                            }
                        })                        
)
.flatMap(response =>{
    return port.write('Your sms message\x1A\r');
})                             
.subscribe(r =>{
    console.log('SMS sent)
});
