This is a code that captures the serial port data and transfer it to the GUI frame in the JTextField. I used the terminal console to check if all data were captured, it captured all of the data. When I added the str0.setText(cell[0]) in the scanner, the flow of data stops at cell0, and what appears to the frame are only the 2 cells (cell 0 and cell 1 data) then it freezes.
