The whole point Ian, is that third party software should
use the latest
version of the manufacturers DLL (which is freeware),
then the download
and validation performed by via program will be up
to date by default.
In other words, the manufacturer's DLL becomes an integral
part of the
analysis software.
I would expect that when these DLLs become available,
writers of
analysis packages will not be slow to interface into
them. The interface
is published in the Flight Recorder Specification Document
and has been
for some time.
If that were so, Tim, then downloads using e.g. SeeYou
would be identical in validity to those used by Filser's
latest freeware [even if that is not itself fully Windows-compatib
le]. But that is demonstrably not the case, to the
extent that the SSA specifically advises against using
SeeYou for badge/record downloads.
When/if a DLL for LXNavigation products becomes available (not Filser,
they just market it) the DLL can be used by both SeeYou and other
programs as it should be invisible what program has performed the
download.
I don't use SeeYou, but TaskNav calls the DOS program to perform
downloads for various recorders. This can create problems and many
people have reported these, especially when the serial port connection
is via a USB adapter. When the application (whatever it may be) can
simply call a manufacturer's DLL and run the whole thing as a Windows
Task I expect to see a vast reduction in download failures.
I hope that SeeYou and Filser both have someone who
reads ras !
AIRC, SeeYou and LXNavigation are written by the same team. They have
been aware of the need to produce a DLL, but so far nothing has been
forthcoming. I would not dream of discouraging anyone from mailing them
@lxnavigation.si and @seeyou.ws
Perhaps some pressure from their clients would help concentrate their
minds. It is hard to see what more IGC can do to progress this.
OK, they could cancel their approval until they do conform, after all it
is now part of the specification for an Approved Recorder, but I would
guess that would be as welcome as a fart in a space suit.
Over to you...
