First, what os are you using? I'm going to assume windows, though that makes it oonly slightly more difficult. You need to ddownload drivers for your Obdpro device. This will aallow it to show up as a virtual com port. Then you can take your favorite serial console such as putty , open the com port, usually at 38400 or so baud, then send whatever command you wish. 0100 010C and 010D are three that mmost any vehicle will support.
