Some leads:

• java2s has some examples.
• this CommPortOpen class can give you a good start.

For reading from the serial port, have a look at the javacomm API here: http://java.sun.com/products/javacomm/

The User's Guide has more information and some example code: http://java.sun.com/products/javacomm/reference/docs/API_users_guide_3.html

For a multi-platform application, look into rxtx.

javax.comm has not had active development for a number of years. The rxtx project has a compatible api as well as a more feature rich gnu package API.

There are examples with the source code and in the Wiki.
