 * Target-To-Host Test:
 *____________________________________________________________________
 * - Sends 100 integers, one at a time via RTDX_write().
 * - Uses ONE output channel.
 *
 * - Tests Data transmission from target to host at the User layer.
 * - This is the module to be run on the TARGET.
 * - This program is meant to be used with the RTDX Diagnostics
 *   Control's Target-To-Host test option.
