The following links are to a class that gives us the ability to open a com port
and send a few commands and then retrieve information from the PR-715. This has
not implemented even a fraction of the commands. It is here as a template for
further use, in conjunction with the documentation provided here.
PR715.txt - a reference for what values need to be sent
across the COM port for one of the functions in the pr715 class.
pr715comm.cpp - the driver (VERY SIMPLE INTERFACE).
