 Play RTTL formatted ringtones on the Roomba.
 <p>
 Run it with something like: <pre>
 java roombacomm.RTTTLPlay /dev/cu.KeySerial1 'tron:d=4,o=5,b=200:8f6,8c6,8g,e,8p,8f6,8c6,8g,8f6,8c6,8g,e,8p,8f6,8c6,8g,e.,2d'<br>
 Usage:
 roombacomm.RTTTLPlay serialportname [protocol] rttl_string [options]<br>
 where:
 protocol (optional) is SCI or OI
 rttl_string is a string of notes
 [options] can be one or more of:
 -debug       -- turn on debug output
 -hwhandshake -- use hardware-handshaking, for Windows Bluetooth
 -nohwhandshake -- don't use hardware-handshaking
 -flush       -- flush on sends(), normally not needed
