Thank you,

as reference I was speculating that perhaps proper values for p1, p2 would
do the trick:

def _getTrackInfo(self, track, p1, p2):
 query = self.formatQuery('1806 02201001 %w %w %w ff00 00000000', track,
                          p1, p2)
 reply = self.send_query(query)
 return self.scanQuery(reply, '1806 02201001 %?%? %?%? %?%? 1000 ' \
                       '00%?0000 %x')[0]
