Marcus,

Another thought: I see that your serial interface has:
   END OF LINE character                              [^@]
  2nd END OF LINE character                          [^?]

The Hopf card normally sends LF/CR at the end of each data record.
My gut feeling is that you should set the serial interface to expect
^j and ^m (instead of ^@ and ^?).

Does your Hopf receiver have a pulse-per-second (PPS) output signal?
I typically see timing variations around +/- 5ms on the serial
telegrams,
but the PPS is much better: +/- 0,5ms.

Paul
