SerialPort version: 5.0.0-beta3 NodeJS Version: 7.4.0 Operating System and Hardware Platform: macOS Sierra. Also observed on Ubuntu 16.04 (ia32) Are you using an alternative NodeJS runtime? (eg Electron): Both vanilla node and Electron

Summary of Problem

Two successive writes to a thermal printer causes node to crash with Abort Trap: 6

Steps and Code to Reproduce the Issue

const SerialPort = require("serialport");
const port = new SerialPort("/dev/cu.usbserial", {baudRate: 9600}, _ => {
    port.write("Hello World\n");
    port.write("Hello World\n");
});

Expected result

Printer prints

   Hello World
   Hello World

Actual result

Printer prints

    Hello World

Then node crashes with the error Abort Trap: 6

Also having this problem code below:

const port = new SerialPort('/dev/tty.usbserial-FT9JAO38', {
  baudRate: 115200,
 });

const Readline = SerialPort.parsers.Readline;
const parser = port.pipe(new Readline());

parser.on('data', (data) => {
  console.log(data);
});

port.on('open', () => {
  console.log('Opened Port')
  write();
})

function write() {
  port.write('Hello', function () {
    port.drain();
  });
  port.write('World', function () {
    port.drain();
  });
}

Error: Abort Trap: 6

SerialPort version: 4.0.7 babel-node 6.11.4 macOS Sierra 10.12.4

Same issue when writing more than one time.

calling drain() as described here https://github.com/EmergingTechnologyAdvisors/node-serialport/issues/660#issuecomment-259525365 fixed it.

This is probably fixed in serialport@5.0.0-beta6 I'm going to close this in favor of #1188 which is a duplicate but active issues to this one.
