Stepper motor control via serial

Hi I have a stepper motor and PCB from www.milinst.com and have connect the device to my PC through the serial. When using the downloadable application
for the device, I receive a comms error.
Does anyone know how to send data to the device to get the motor to turn?

You need to setup the serial port to be operating the same as the device. Should be in your SW somewhere.
