    • isSynced

      boolean isSynced()

    • requestResync

      void requestResync(String reason)
      Stop decoding and ask the reader to start its Raw encoding stream again. Decoding resumes once the reader acknowledges the Reset Encoding State.
      Parameters:
      reason - why, for the log

    • resendResetIfNeeded

      void resendResetIfNeeded()
      Send another Reset Encoding State unless one is already waiting for its reply.

    • checkSpeedTimeout

      void checkSpeedTimeout()
      Give up on a speed change that never got an answer, so polling can start at 8 kbps.

    • speedCheckDone

      void speedCheckDone(boolean ok)
      The Get Info that follows a speed change has been answered or has failed.
      Parameters:
      ok - true if the board answered at the new speed

    • resetReplied

      void resetReplied(boolean ok)
      The reader answered a Reset Encoding State.
      Parameters:
      ok - true if it was accepted

    • restartAfterReconnect

      void restartAfterReconnect()
      Forget the old link state and change speed again from 8 kbps, after the port was reopened.

    • retrySpeedIfDue

      void retrySpeedIfDue()
      Called from the poll loop: if a speed change fell back to 8 kbps (often because track power was still off), try 62.5 kbps again once the retry time has come.

    • processRawReply

      void processRawReply(Dcc4PcReply r)
      Decode one Get Data reply and update the sensors and reporters. Called on the packet processor thread, in the order the replies arrived.
      Parameters:
      r - the reply

    • forgetPomPackets

      void forgetPomPackets()
      Forget the POM packets seen so far, after packets were lost to an overflow. A lost packet may have been a newer POM packet, so a later answer may be for a CV we never saw; crediting it to the last one seen would give that CV the wrong answer (2026-10-15). Answers count again from the next POM packet seen.

    • decodeDCCPacket

      void decodeDCCPacket(int[] packet)

    • decodeDCCPacket

      void decodeDCCPacket(int[] packet, long now)
      Decode the DCC packet a RailCom cutout followed: sets addr, dcc_addr_type and cvNumber.

      A decoder may answer a POM packet in the cutout after a later packet to it, not the POM packet itself. With only one loco in the command station's refresh that is nearly always the case (2026-10-15: the answer to "write CV 31" followed a speed packet). So after any packet to a loco, cvNumber is the CV of the last POM packet seen for it, if that was within POM_ANSWER_WINDOW.

      Except the first STALE_CUTOUTS cutouts to the loco from the first POM packet for a new CV: there the decoder may still send its previous answer (2026-10-16, ESU LokSound 5: usually exactly one stale cutout). Crediting them gave every CV the value of the one read before. After an overflow, any POM packet counts as new, as a newer one may have been lost.

      Parameters:
      packet - the DCC packet bytes
      now - the current time in ms

      int getInputs()

    • getDescription

      String getDescription()

    • getVersion

      String getVersion()
