serial communication question

this is the easiest question you will answer today, i promise. I would jsut test it myself buuuut I may have made my arduino a biiiiit not worky worky.

if I try to write the value 400 to the serial port, what comes out the port? say for example

Serial.print(400); or Serial.write(400);

I know it compiles, but that is about it.

Serial.print(400) will send '4', '0', '0' to the serial port.

Serial.write(400) will send 144 to the serial port - the write() function takes a byte, so only the low order byte (containing 144) is sent. The high order byte is ignored.
