I'm assuming you mean you need to send binary data, as opposed to ASCII data,

depends on how you need/want to build the packet, but I use a string buffer...

StringBuffer packet = new StringBuffer();

packet.append((char) 0x01);
packet.append((char) 0x2B);
packet.append((char) 0x0D);
packet.append((char) 0x0A);

// etc...then

dv.sendString(packet.toString());

you could also use a character array
