serialport.list returns no data

[24X7]

I have a MacBook Pro running windows bootcamp (does not seem to be the issue though) and it is not able to list any of the ports nor connect. Am I missing something?

[reconbot]

Can you give us some sample code? What version of node are you running? And lastly, What does the serialportlist command output? (you might have to find it in your node-modules/bin directory)

[24X7]

Yeah... pretty simple... The array printed is empty. "[]"

require('serialport').list(function (err, results)
{
if (err)
{
throw err;
}

console.log(results);

});

The version of node, and the version of windows?

[24X7]

Node is 0.10.32 and windows is 8.1. Note I do not have the issue on OSX.

Have you installed the FTDI drivers

So I have drivers for the devices installed. I did not however install anything from the FTDrivers site. Is this required if you already have drivers installed?

Can anything see the com port?

I am seeing the same thing on TurnKey Linux 12.0 / Debian 6.0.10 Squeeze. I did noticed is that in "serialport.js" Line: 658. The default (for my platform) is "listUnix". My "process.platform" equates to "Linux".

Looking at "listUnix" line 510 and 525, '/dev/serial/by-id' is used. It doesn't look like that is used on (at least my version of) Linux. It looks like it separates out the device types.

find /dev -name "by-id"
/dev/v4l/by-id
/dev/snd/by-id
/dev/disk/by-id

For reference:

uname -a
Linux nodejs 2.6.32-5-686 #1 SMP Tue May 13 16:33:32 UTC 2014 i686 GNU/Linux

node -v
v0.10.2

@24X7 can you run node -e 'console.log(process.platform)'

[haydockjp]

node -e 'console.log(process.platform)'
linux

[haydockjp]

I also get the same on my raspberry pi

uname -a
Linux raspberrypi 3.12.28+ #709 PREEMPT Mon Sep 8 15:28:00 BST 2014 armv6l GNU/Linux

node -e 'console.log(process.platform)'
linux

@haydockjp you probably have a similar but different issue then @24X7

[haydockjp]

Sorry, I think I should be watching #343

I have this same issue on windows 7, with node version 6.9.5 and serialport v4.0.7,
I cannot list any ports on the machine. I can see the COM4 port in Devicemanager on Win7.

_

`var SerialPort = require("serialport");
var util = require("util"), repl = require("repl");

SerialPort.list(function (err, ports) {
ports.forEach(function(port) {
console.log(port.comName);
console.log(port.pnpId);
console.log(port.manufacturer);
});
});

var serial_port = new SerialPort("COM4", {baudrate: 57600});

console.log("Writing '*IDN?' to the serial port");
serial_port.write("*IDN?\r");

serial_port.on("data", function (data) {
console.log("here: "+data);
})
serial_port.on("error", function (msg) {
console.log("error: "+msg);
})

serial_port.close();`

_

Also I tried with the following code

`var Serialport = require("serialport");

var Serialport = new serialport("COM4", {
baudrate : 57600,
startbits : 1,
stopbits : 1,
parity : "none",
parser: Serialport.parsers.readline("\n")
});

Serialport.list(function (err, results) {
if (err) {
throw err;
}

for (var i = 0; i < results.length; i++) {
var item = results[i];
console.log('{comName,-15} {pnpId,-20} {manufacturer}', item);
}
});`

And finally tried to run the (node serialport-list.js) directly from the bin . It never shows anything.

Can someone please help me ?

Can you open a new issue and fill out the template? serialport-list is a good indicator if your install and setup are working correctly.
