Having Arduino and Gobetwino wait for eachother to continue

so have been working on project has stepper motor , driver turn amount of microsteps , stop, wait button press , continue on until maximum amount of button presses reached.  using arduino uno r3, , following driver/motor.

now have functioning code , want replace button press actual intended function. want stepper move , send signal gobetwino hit "enter" button. take light measurement in excel sheet controls cl 200a light meter. want arduino wait until measurement finished , have gobetwino tell arduino continue. should repeated until maximum amount of measurements has been reached.

i have looked through gobetwino manual , looked around online, have not found whether or not done or whether there may other alternative?
any ideas appreciated!

} 
    if (state == 2 && buttonpresscount < x)

      {
       digitalwrite(led,low);
       stepper.move(stepsize);
       buttonpresscount++;
       state = 3;                            //state 3

      if (state == 3)
      {
         if (stepper.distancetogo() == 0)

i want arduino wait until measurement finished

what options available tell when measurement finished?
