How can I use the CEI-x20 API to create an internal or external wrap around test of a user-specified channel pair for a CEI-x20 device?

This is a simple sample application that sends out some data on a user-specified transmit channel and reads it back on a user-specified receive channel. In internal wrap mode, the receive channel must be the same-numbered channel as the user-specified transmit channel. In external wrap mode, any receive channel can be specified by the user as long as a properly connected external wrap connector is installed.
