+     *
+     * @details  This is a blocking call that will send a command
+     *           to HTMGT.
+     *
+     * @note     If o_rspLength is returned with a non-zero value,
+     *           the data at the o_rspData should be dumped to
+     *           stdout in a hex dump format.
+     * @note     The maximum response data returned will be 4096 bytes
+     *
+     * @param[in]      i_cmdLength  number of bytes in pass-thru command data
+     * @param[in]     *i_cmdData    pointer to pass-thru command data
+     * @param[out]    *o_rspLength  pointer to number of bytes returned
+     *                              in o_rspData
+     * @param[out]    *o_rspData    pointer to a 4096 byte buffer that will
+     *                              contain the response data from the command
+     *
