  7.  You can check the receiver state by using the public semaphore "DCF77 State". 
  8.  
  9.  
  10.  struct DCF77StateList
  11.  {
  12.     struct SignalSemaphore sl_Semaphore; // the Semaphore "DCF77 State"
  13.     STRPTR Version; // Pointer to DCF77 version number
  14.     BOOL Received;  // FALSE: no DCF77 time | TRUE: system clock was set by DCF77.
  15.  
  16.     // The values below are introduced with DCF77 version 2.18:
  17.     LONG ReceiverState; // 0 - No signal. 1 - Receiving disturbance.
  18.                         // 2 - Wait for synchronization. 3 - Receiving.
  19.                         // 4 - Program inactive.
  20.     LONG TimeLeft;  // expected time left [s] to finish off
  21.     LONG LastError; // not yet implemented
  22.  };
  23.

  25.  The source code of the shell commands in this drawer contains example code for
  26.  the check of the DCF77 receiver state. WaitDCF77ifCrash uses all possible
  27.  functions.
