How to send data to COM PORT using JAVA?

Question

Friends, I want to connect and transfer data to COM PORT (either virtual or original) in JAVA?

Answer 1

The Java Communications API (also known as javax.comm) provides applications access to RS-232 hardware (serial ports)

Answer 2

An alternative to javax.comm is the rxtx library which supports more platforms than javax.comm.

Personally I recommend SerialPort from http://serialio.com. From experience, I strongly do not recommend the Sun or IBM serial IO implementation, nor RxTx. Refer to my answer on some of the aforementioned questions.
