Sorry but this code didn't work for me, cause I'm on a Mac and it can't get
port numbers, only names. Anyway initialization is not the problem: this
SerialPort2 class uses two methods called *getOption:* and
*setOption:to: *which
get and set these port parameters (baud rate, data bits, flow control...
even handshake settings). Now after starting the program I'm getting default
settings on a transcript window and they seem ok:

1. baud rate: 115200
2. data bits: 8
3. stop bits: 1
4. parity type: 0
5. input flow control type: 0
6. output flow control type: 0

20. DTR: 1
21. RTS: 1
22. CTS: 0
23. DSR: 0
24. CD: 0
25. RI: 0

Then that's not the problem... I guess that the way I'm sending bytecodes
it's not correct, because there's no response from board.

Thanks again :)
