/**
 * @brief   Raw Commanding and Wiretapping of devices.
 * @details
 * Full Documentation: ECSS-E-ST-70-41C or ECSS-E-70-41A
 * Dissertation Baetz p. 115, 116, 165-167.
 *
 * This service provides the capability to communicate with devices in their
 * native protocols with raw commands through the DeviceHandlerIF.
 *
 * This is a gateway service. It relays device commands to the software bus.
 * This service is very closely tied to the CommandingServiceBase
 * template class.
 *
 * There are 4 adaption points for component implementation through the
 * CommandingServiceBase.
 *
 * This service employs custom subservices exclusively.  This includes a
 * wiretapping subservice to monitor all traffic between target devices and
 * this service.
 *
 *   - TC[2,128]: Raw Commanding
 *   - TC[2,129]: Toggle Wiretapping
 *   - TM[2,130]: Wiretapping Packet TM
 *   - TM[2,131]: Wiretapping Packet TC
