OS X 10.9.5 PortListener and DataListener

[RishiGupta12]

Please raise (just copy -paste issue) on google group and let us follow it there.

• Version mismatch is not an issue.
• The error reporting from dataListener i.e. method onDataListenerError(int arg0) gets called whenever there is an error. Because USB device is removed error continue to occur. This is why this method is called again and again. The onDataListenerError is intended to trigger system recovery policy to write recoverable and fault tolerant application. Read javadoc here http://www.javadoc.io/doc/com.embeddedunveiled/scm/1.0.3
• SCM does not allow to unregister any listener until port which it is monitoring is closed. But I can see that something more graceful is needed here.
• If the usb device is removed and plugged again into system, it is seen as a new device by both OS and SCM. Device may or may not be assigned same name for example if previously it was ttyUSB0 now it may be ttyUSB1. So if there is a registered data listener it can not automatically open newly plugged device and start watching it.
• No need of creating new instance of SCM or playing with JVM. I am going to resolve the issue more gracefully.

This test is passing https://github.com/RishiGupta12/serial-communication-manager/blob/master/tests/test56-dl-removePort/src/test56/Test56.java

Please take a look at when error occurs, 1st unregister listener(s) and then close port. Now if you plugin the device again, open port and register listener.
