Serial port emulation

In order to emulate the serial port and send custom DTMF sequences, follow the manual:

1. Open a new terminal window and run the following command to allocate a pseudo-terminal.

   socat -d -d pty,raw,echo=0 pty,raw,echo=0

   You will get something like this:

   2017/01/28 16:43:09 socat[13278] N PTY is /dev/pts/20
   2017/01/28 16:43:09 socat[13278] N PTY is /dev/pts/21
   2017/01/28 16:43:09 socat[13278] N starting data transfer loop with FDs [5,5] and [7,7]

2. Launch server with --port option:

   node BE/server.js --port=/dev/pts/20

3. Send DTMF sequences to the second PTY port:

   echo 0108 > /dev/pts/21
