We manufacture a product that uses a stepper motor controller. We
communicate with the stepper motor controller through a serial port.
We have different configurations of this product. We also have
several generations of this product that are using different stepper
motor controllers. Because of this we also have several different
versions of the software available to cover the different unit. I am
in the process of re-writing the software with the idea of having one
version cover all our different units. What I would like to know is
if it is possible to identify which unit is plugged into the serial
port so the software will load the appropriate driver and
configuration? I was thinking maybe something could be built into the
serial cable that would be specific to a unit? Any ideas would be
helpful.
