What do you want ?
Using the LCDC software works, but what is the next step ?
Do you want serial ports on your PC to connect a few displays ? or do you want usb plugs to connect to the displays ? Or perhaps a single Arduino that controls a whole bunch of them ?
If you want a simple serial terminal, you could try the Q Serial Terminal, http://qst.sourceforge.net/
That way you don't have to start the Arduino IDE.
