I have added the line of correction in this area. Hope somebody can confirm there was indeed an error before.
Changes are you already used screen or that it's at least installed by default on your GNU/Linux system; it can connect to the serial line as well:
screen /dev/ttyUSB0 115200
2009.08.13 CORRECTION by CqCn: In the above should it not be ttyUSB1 ?? That is what connects for me!
