Not receiving "disconnect" event on Linux

[franxois]

Hello,

Here is the code I test on windows

var SERIALPORT = require("serialport");
var serialPort = SERIALPORT.SerialPort;

var listAndConnect = function ()
{
    SERIALPORT.list(function (err, ports) {
        ports.forEach(function (port) {
            console.log("opening " + port.comName);
            var sp = new serialPort(port.comName, {
                parser: SERIALPORT.parsers.raw
            });

            sp.on("data", function (data) {
                console.log(port.comName + ": " + data);
            });

            sp.on('disconnect', function (err) {
                console.log('on.disconnect');
                setTimeout(listAndConnect, 2000);
            });

            sp.on("close", function () {
                console.log("on.close");
            });

            sp.on("error", function (err) {
                console.log("on.error");
                console.log(err);
            });
        });
    });
};

listAndConnect();

The script list COM port, connect to them and echo the data on input. When it receive the disconnect event, it wait 2 seconds before listing and connecting again.

• On windows :
  node 0.10.32, latest nodeserial. I use usb FTDI device or usb arduino.
  As expected, when I unplug the usb device, the program goes to the disconnect event.
• On linux :
  i5 with Ubuntu 14.04 64bit, last node
  Raspberry Pi, raspbian & node 0.10.28
  When I unplug, the message "on.disconnect" never appears. node hangs, the CPU goes to 100%.
