node-serialport是一个Node.js的包，用来对串口数据进行读写操作。
基本示例代码：
var SerialPort = require("serialport").SerialPortvar serialPort = new SerialPort("/dev/tty-usbserial1", { baudrate: 57600}, false); // this is the openImmediately flag [default is true]serialPort.open(function (error) { if ( error ) { console.log('failed to open: '+error); } else { console.log('open'); serialPort.on('data', function(data) { console.log('data received: ' + data); }); serialPort.write("ls\n", function(err, results) { console.log('err ' + err); console.log('results ' + results); }); }});罗列所有串口：
var serialPort = require("serialport");serialPort.list(function (err, ports) { ports.forEach(function(port) { console.log(port.comName); console.log(port.pnpId); console.log(port.manufacturer); });});串口配置：
baudRate
dataBits
stopBits
parity
rtscts
xon
xoff
xany
flowControl
bufferSize
parser
encoding
dataCallback
disconnectedCallback
