i have gotten simulator start communicating me (see past question); however, not know saying me. here simple code sends message simulator. 

`import serial  port = '/dev/tty.usbserial-pxfo5l2l' baudrate = 9600 timeout = 1 ser = serial.serial(port = port, baudrate = baudrate, timeout = timeout)  ser.write('volt:level 4') `
