i have been using processing for a few weeks now and i have started to build an interface for a cars ECU to display all kind of car data. I am using the serial lib to do the comms. but im having a slight problem. prob something very simple, but for the life of me, i cant work it out. i need to send a carriage return at the end of each command. does anyone know how to do this. 

i can do it via arduino by serial.println(), but serial.write() in processing as far as i can see does not. 

thanks in advance for any help.
