I guess the first few lines are remnants of what is stuck in the OS serial input buffer from AnalogReadSerial, but I'm not sure what's going on before ASCIITable starts properly.
How can it be? I mean... there is a sketch upload beetween AnalogReadSerial and ASCIIITable output, the only way is that RXTX keeps the last read buffer even if you close and open the serial port.
