 *   at MPRINTF_MAX_ADDR. MPRINTF_WRAP_COUNT is decreased
 *   whenever saving restarts at MPRINTF_START_ADDR. If the
 *   position is MPRINTF_MAX_ADDR and the counter is zero no data 
 *   is saved. Before output is saved, it is stored in a buffer that is
 *   MPRINTF_BUFFER_SIZE bytes. If the output has more bytes, then
 *   that may lead to corruption.
