I triede with fpc 2.4.4 but nothing changes. Would you mind having a
look a the full dll with your more recent fpc?
By the way, how do I install fpc 2.5.x ??
I might send it to you privately; the only trouble is that you don't
have a real hardware to connect it, even if the transducers class are
created during the main device creation and their count and status are
(should) always be available even if not connected.
A test case would simply:
1) createoleobject //OK
2) object.transducers.count // OK, always 8
3) object.transducers(1).Status // ???? should be an integer, not
a crash !!!
