Port cannot be accessed by another device after closing [OSX 10.10]

[bolandrm]

I am opening and using a serialport via node-serialport. When I close the serial port, it seems I still cannot access it from other programs. I am getting a success callback on closing the port.

When I make a subsequent call to close(), just to double check, i get this:

currentSerialPort.close(function(e) { console.log(e); })
VM831:2 Error: Serialport not open.(…)

So it seems that node-serialport does think the port is closed.

When I try to access the port with another program I get:

stty: /dev/tty.usbmodem747851: Resource busy
make: *** [burn] Error 1

Completely closing my Electron application which is using node-serialport resolves the issue.
