Turns a PC into a multi-channel pulse generator utilizing the parallel port. The period, duty and phase of each channel are adjustable so as to be used in PWM systems as well as in testing servo and stepper (stepping) motors. If you have an old PC, boot it by dos to run PulsePar and control it by SeriCon on your GUI PC through serial port. The free trial version of SeriCon is enough in many cases.
