Question

经过仔细搜索，我找不到文档告诉我第二个参数有哪些选项及其作用到新的SerialPort（）

Answer 1

由于缺少更好的描述，Node Serialport文档非常糟糕。它以一种非常荒谬的方式进行布局，并将关键信息隐藏在奇怪或切向的主题标题下。

我想我明白你的追求；创建新的Serialport对象时可以在路径后传递的openOptions对吗？然后应如下所示：

/**
 * @typedef {Object} openOptions
 * @property {boolean} [autoOpen=true] Automatically opens the port on `nextTick`.
 * @property {number=} [baudRate=9600] The baud rate of the port to be opened. This should match one of the commonly available baud rates, such as 110, 300, 1200, 2400, 4800, 9600, 14400, 19200, 38400, 57600, or 115200. Custom rates are supported best effort per platform. The device connected to the serial port is not guaranteed to support the requested baud rate, even if the port itself supports that baud rate.
 * @property {number} [dataBits=8] Must be one of these: 8, 7, 6, or 5.
 * @property {number} [highWaterMark=65536] The size of the read and write buffers defaults to 64k.
 * @property {boolean} [lock=true] Prevent other processes from opening the port. Windows does not currently support `false`.
 * @property {number} [stopBits=1] Must be one of these: 1 or 2.
 * @property {string} [parity=none] Must be one of these: 'none', 'even', 'mark', 'odd', 'space'.
 * @property {boolean} [rtscts=false] flow control setting
 * @property {boolean} [xon=false] flow control setting
 * @property {boolean} [xoff=false] flow control setting
 * @property {boolean} [xany=false] flow control setting
 * @property {object=} bindingOptions sets binding-specific options
 * @property {Binding=} Binding The hardware access binding. `Bindings` are how Node-Serialport talks to the underlying system. Will default to the static property `Serialport.Binding`.
 * @property {number} [bindingOptions.vmin=1] see [`man termios`](http://linux.die.net/man/3/termios) LinuxBinding and DarwinBinding
 * @property {number} [bindingOptions.vtime=0] see [`man termios`](http://linux.die.net/man/3/termios) LinuxBinding and DarwinBinding

例如，要创建一个波特率为9600且没有奇偶校验的新SerialPort对象：

var newPort = ("OS-appropriate comName here", { baudRate:9600, parity:"none"});

出于某种原因，它埋在文档中而不是放在前面和中间：https://serialport.io/docs/api-stream

node-serialport新的SerialPort选项的文档在哪里？
