Answer 1

You need to read the data from the serial port in a different thread to that used to display the dialog box. I'd recommend reading the Concurrency in Swing lesson from Sun.

Answer 2

A JOptionPane is a modal dialog, and can not be tuned. A modal dialog blocks the invoking thread.

If you don't want to create another thread (which seems indeed to be the best method), you must create your own dialog window, with JDialog class.

You can watch JDialog tutorial.
