写了一个demo，放到源码下面编译，对dev/ttyMT1进行操作，在系统的init.rc里面要把dev/ttyMT1的权限改一下才能读写。

nrComm Lib 9.47 Copyright (C) 1997-2017 Roman Novgorodov, DeepSoftware LLC
1. General information
======================
nrComm Lib provides some tools for performing the serial communications
tasks in Delphi/CBuilder development. It has ready solutions for many
communication tasks and supports working with different types of devices:
* RS232, serial ports (native and virtual), USB2RS232 adapters etc.;
* Telephone API (TAPI) devices (data and voice modems);
* Text to speech conversion with voice modem output;
* direct access to LPT port;
* barcode readers;
* Bluetooth connections and devices;
* GSM (sms send receive, access to phonebook etc.);
* ZModem, Kermit file transfer protocol;
* HID (Human Interface Devices) devices;
* Terminal control with VT100 support;
* USB - device detection, WinUSB or lightweight nrUsb.SYS installation, I/O operations;
* ready solution for implementation any data packet protocol TnrDataProcessor component
* 32bit and 64bit are full support. All needed drivers are signed and can be installed on x64 Windows;
* GPS
* event logging and other more.
After installation nrComm Lib you will find amny demo projects (with sources) and see the
context help files and documentation.

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").SerialPort
var 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：baudRatedataBitsstopBitsparityrtsctsxonxoffxanyflowControlbufferSizeparserencodingdataCallbackdisconnectedCallbackplatformOptions - sets platform specific options, see below.目前已有很多项目在使用这个包进行串口处理：Johnny-Five - Firmata based Arduino Framework.Cylon.js - JavaScript Robotics, By Your Command.node-l8smartlight (source) A node library to control the L8 Smartlight via Bluetooth or USB portfirmata Talk natively to Arduino using the firmata protocol.tmpad source - a DIY midi pad using infrared, arduino, and nodejs.

python串口读写源代码程序+详细注释
简单的python串口读写介绍
ser serial Serial 0 是打开第一个串口
print ser portstr 能看到第一个串口的标识 windows下是COM1
ser write “hello" 就是往串口里面写数据
ser close 就是关闭ser表示的串口
ser open 会打开这个串口
