It's possible to know that port is busy (TYPEPORTBUSY) by using TIOCEXCL directive in.nix native library, but using of this directive make some troubles in Solaris OS, that's why TIOCEXCL not used in Solaris (!) Be careful with it. Also Solaris and Mac OS X versions of jSSC not support following events: ERR, TXEMPTY, BREAK. SerialPort provides highly flexible control of serial ports from your Java application. SerialPort is a high-performance class that also provides low-level serial port control. If your device plugs into a serial port—on or off the Internet—it is almost certain that you can use SerialPort to communicate with it.

What is jSerialComm?

Like so many other Mac users on 10.6 to 10.7 with the loss of serial port choices, I'm disappointed that I can't use my Arduino. Perhaps an option would be to use a bluetooth/wifi interface but I feel for now I've lost the faith. Serial Monitor Output: processing.app.SerialException: Serial port '/dev/tty.Bluetooth-Modem' already in use. This is code for the Linux version - the biggest change will be the serial port name (the '/dev/rfcomm0') part. I don't have my Mac here so I'm sorry I forget the name of the Mac device but it is in /dev - something with Bluetooth if I remember correctly. All this sample does is read bytes off of the serial (USB) port.

Java Serial Port Mac Os X 10.10

jSerialComm is a Java library designed to provide a platform-independent way to access standard serial ports without requiring external libraries, native code, or any other tools. It is meant as an alternative to RxTx and the (deprecated) Java Communications API, with increased ease-of-use, an enhanced support for timeouts, and the ability to open multiple ports simultaneously. Address book cleaner for mac.

Some of the features of this library include:

Platform-independent library deployment (automatically uses correct native library based on current architecture)
Very lightweight and efficient implementation
Enumerates all available serial ports on a machine
Returns both a system port description and a friendly device description
User-specifiable port descriptors including symbolic links
Configurable ports according to baud rate, data bits, stop bits, and parity
Configurable port timeouts (blocking and non-blocking) for both reading and writing
Configurable flow control parameters for the serial port (CTS, RTS/CTS, DSR, DTR/DSR, XOn/XOff)
Ability to read and write raw data bytes directly to the serial port
Ability to read and write byte streams via Java's InputStream and OutputStream interfaces
Event-based reading and writing via callbacks
Callback notification when:

New data is available for reading
All data has been successfully written
A complete fixed-length data packet has arrived
A delimited string-based message has been received

Additionally, this library can be used in any Java project intended for use on the following platforms:

32/64-bit Windows 7 or later
32/64-bit Mac OS X Tiger (10.4) or later
32/64-bit Linux distributions
ARM/Intel/AMD Mobile Linux derivatives (e.g. RaspberryPi, Beaglebone, etc.)

How can use this library in my own project?

One of the most convenient features of this library is that it allows you to simply include the JAR file in your custom project, and it will automatically select and load the correct native library for your platform and architecture. As such, you can make use of this library by simply copying the jSerialComm.jar file into your project directory and linking to it as you would any other JAR file.

To access the contents of the library in your project, make sure to import com.fazecast.jSerialComm.* into your java files. You can then generate a list of all available serial ports on your system (real or virtual), by calling the following static method:

This will return an array of SerialPort objects through which you can iterate. See the Javadoc Library Reference for a complete overview of this library and its methods. Alternately, if you already know the port descriptor of the port you wish to use (e.g., '/dev/ttyS0' or 'COM3'), or if you are using this library with pseudo-terminals (e.g., '/dev/pts/14'), you can create a SerialPort object using the following static method:

Note for Linux users: Serial port access is limited to certain users and groups in Linux. To enable user access, you must open a terminal and enter the following commands before jSerialComm will be able to access the ports on your system. Don't worry if some of the commands fail. All of these groups may not exist on every Linux distro. (Note, this process must only be done once for each user):

Replace the username parameter with your current username. Hear for mac serial number lookup. (If you are not sure what your username is, type whoami and it will tell you.) If you are using SUSE 11.3 or higher, replace the '-a -G' flags with a single '-A' flag. Log out and you should have access to the serial port after logging back in.

Additionally, if you are using an automated build system (such as Maven), you can import this library directly into your project as a dependency from the Maven Central Repository instead of copying the .jar file manually. Use one of the following dependency declarations depending on the build system you are using:

Are there any usage examples?

Although this library was designed to be as simple and flexible as possible, you can enable a number of different modes of operation via manipulation of the serial port timeout values and the interface through which you choose to access the serial port.

For a description of the various modes of operation available in this library, please refer to the Modes of Operation wiki article. For code-based examples of how to use this library in your own project, we provide a Usage Examples wiki.

Finally, you can view the API Documentation for further information on how to use this library.
