Im making a java GUI on Netbeans to run on a computer that will be connecting to device through a serial port. This GUI is to show the user information that will be stored in the other device. Like a text file or to retrieve some data from the device's sensors. I just finished the outline of the interface and now it is the harder part as this is the first time dealing with serial ports. The other device is a beagleboard.I am a little unsure on where to even start, as I have looked in this forum but nothing seems to relate to my question exactly. I assume I should establish a connection through the port with the device and send the requests for the info as the user requests.
Any advices?Should the connection be established in a separate java class of the program? The gui is made up of a main JFrame and two auxiliary ones and I (plan) have a button to estabish the connection in the main frame basically.

How To Connect Serial Port Using Java
Yes. One java class should be sufficient to establish the connection, send messages to the beagleboard, and receive responses. Backbreaker online game free.
I assume I should establish a connection through the port with the device and send the requests for the info as the user requests.
Yes. You would format the requests in whatever format the beagleboard requires.
Here's a class I put together to make sure a single instance of the Java application ran. You would modify this for your communications.

This question has been asked and answered many times:
to reference a few.
Personally I recommend SerialPort from http://serialio.com - it's not free, but it's well worth the developer (no royalties) licensing fee for any commercial project. Sadly, it is no longer royalty free to deploy, and SerialIO.com seems to have remade themselves as a hardware seller; I had to search for information on SerialPort.
From personal experience, I strongly recommend against the Sun, IBM and RxTx implementations, all of which were unstable in 24/7 use. Refer to my answers on some of the aforementioned questions for details. To be perfectly fair, RxTx may have come a long way since I tried it, though the Sun and IBM implementations were essentially abandoned, even back then.
A newer free option that looks promising and may be worth trying is jSSC (Java Simple Serial Connector), as suggested by @Jodes comment.

The Java Communications API (also known as javax.comm) provides applications access to RS-232 hardware (serial ports): http://www.oracle.com/technetwork/java/index-jsp-141752.html

An alternative to

is the rxtx
