COMM-DRV++ Standard Edition

COMM-DRV++ is simply the easiest communication C++ class library to use. It insulates the details of serial communication under Windows from the software engineer / programmer.

COMM-DRV++ allows you to accomplish your serial communication task literally in minutes after installation. We have encapsulated general communication functions into easy to understand methods that are applicable to real world applications.

In developing COMM-DRV++, WCSC tabulated a list of the most frequently asked technical questions on serial communications, and tailored its methods to encapsulate these.

The following example is a complete working Windows application that calls another computer and transfers a file to it. Could it be any simpler?

COMM-DRV++ though easy to use is quite powerful. It contains a large number of methods/functions. Though most methods/functions will rarely be used, they are developed for the few times they may be needed. <Click here> to see what our satisfied users think of our products.
