What is that value? "This" or "Thisishow"?

when i say value i want to say numeric value, i don't try char ascii

You can do the same thing with numeric values.
int a=13, b=4572, c=-14;
Code: [Select]
Serial.print(a);
Serial.print(" ");
Serial.print(b);
Serial.print(" ");
Serial.print(c);


or
Code: [Select]
Serial.write(a);
Serial.write(b);
Serial.write(c);


Keep in mind that write()ing non-byte sized variables will result in multiple bytes being sent, and you must reassemble them in the correct order.
