Accessing serial devices from emulator (OSX 64bit/Eclipse Kepler 64bit) about kura HOT 1 CLOSED

Hello Alessandro,

The serial library has been updated to support the OSX emulator. A
couple of notes:

1. The javax.comm implementation in Kura does not support dynamic port
   names. We hope to have this in the future, but are waiting on IP
   approval from Eclipse. So, this means the port names are hard coded in
   the JNI. Port names likes "/dev/ttyUSB0, /dev/ttyS0, /dev/tty.usbserial"
   should work without issue. However, if you have a name such as
   "/dev/tty.usbserial-FTWDSO8Z" you will need to link to a known port:

ln /dev/tty.usbserial-FTWDSO8Z /dev/ttyS0

Then use port name "/dev/ttyS0".

1. There is an outstanding issue in Eclipse regarding the red
   "Terminate" button (read here:
   https://bugs.eclipse.org/bugs/show_bug.cgi?id=38016). In the OSX
   emulator, if you are using a serial port and use the red "Terminate"
   button, this may cause the port to remain locked and can cause system
   crashes. To avoid this, I would first stop the OSGI container in the
   console with 'stop 0', then terminate the JVM.

Let me know if you have problems or have questions.

Thanks,
--Dave

I have some troubles instantiating a serial connection to a modbus
device using the emulator. The hardware is a Serial-to-USB FTDI cable
with a modbus device attached.
This works on the raspberry (I see the FTDI cable as /dev/ttyUSB0) and
the modbus data connection is fine.

However if I try to use the same FTDI cable on my development machine
things don't work.
In my "Run configuration" I specified the VM argument:
-Dkura.ext.dir=/Users/ale/dev/tmp/ to a directory containing
javax.comm.rxtx.properties file declaring the serial port
(/dev/tty.usbserial-FTWDSO8Z).
When I try to access the port Kura says it doesn't exist:

Manually adding the port causes a different error. In Emulator project
MANIFEST.MF I added to /Import-Package/ section the following:
javax.microedition.io, javax.comm;version="1.2.0"
and in Emulator.java I added the following line at the end of
|activate()| method:
|CommPortIdentifier.addPortName("/dev/tty.usbserial-FTWDSO8Z",
CommPortIdentifier.PORT_SERIAL, null);|
