/** @file
 * @brief "No OS" port layer example
 *
 * This port shows you how you can run ucxclient on a system without
 * mutex- and thread support.
 *
 * This example port uses Linux implementation for U_CX_PORT_GET_TIME_MS()
 * and UART driver. Normally you will need to implement this part
 * for your specific target.
