Node Serialport 文档非常糟糕,因为没有更好的描述。它以一种非常荒谬的方式布局,并将关键信息隐藏在奇怪或切题的主题标题下。
我想我明白你在追求什么;在创建新的 Serialport 对象时,您可以在路径之后传递 openOptions ,对吗?那么应该是这样的:
/**
* @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,创建一个波特率为 9600 且无奇偶校验的新 SerialPort 对象:
var newPort = ("OS-appropriate comName here", { baudRate:9600, parity:"none"});
由于某种原因,这被埋没在文档中,而不是放在前面和中心:https://serialport.io/docs/api-stream
