+ This option enables to convert two hexagonal characters 
+ into one binary, and vice versa, which resolves the problem of 
+ XMLSocket which can not handle a 0x00(Null) character correctly. 
+ For example, when you send a "00" command from Flash, 
+ the serproxy with "usehex" option send 0x00 command to your Arduino. 
+ Conversely, when your Arduino says 0x00, the serproxy 
+ with "usehex" option relay "00" string to Flash.
+ This option works well with the combination of XMLSocket class 
+ in Flash and Arduino Firmata, because Firmata command uses 
+ many 0x00 binary in its packets.

  newlines_to_nils=true
  
+ Also, if you use this serproxy with the combination of XMLSocket class in Flash and Arduino Firmata, you are strongly recommended to use "usehex" option like:
+ 
+ usehex=true
+ 
+ This option enables to convert two hexagonal characters into one binary, and vice versa, which resolves the problem of Flash XMLSocket which can not handle a 0x00(Null) character correctly. For example, when you send a "00" command from Flash, the serproxy with "usehex" option send 0x00 command to your Arduino. Conversely, when your Arduino says 0x00, the serproxy with "usehex" option relay "00" string to Flash.
+ 
  To launch serproxy, simply double-click it.  (This version does not require a .command file.)
