It will require quite an effort to convert all my auto-sampler files to
run in SIM mode, but the question is, will it run reliably if I do? I
have changed over the most-used one, and there are occasional system
freeze-ups, though it is hard to tell if they are more frequent than
normal, and even if they are, whether the problem is switching back and
forth between QN and SIM rather than SIM by itself. Why does Bruker
continue to have QN as the default when using SIM puts them into step with
the rest of the world?
On a totally different matter, I have found that non-data files -- in
particular extended parameter files, and probably other types as well --
are not handled properly by the parallel port transfer programs ZZNET and
its newer incarnation nmrnet. Apparently these programs send over to the
pc multiples of the Aspect sectors, even when the files are smaller, with
the result that when they are sent back to the Aspect, the size in the
header is larger and the DISNMR program recognizes them as wrong data
type. Kermit does not seem to make the same mistake, so that files can be
sent back and forth without problem using Kermit. The consequence of this
is that it is not at present possible to make use of the parallel transfer
programs for backing up the Aspect system. Even if the files are
truncated to their correct size on the pc it doesn't help, because then
the program will not send them back. Disappointing, since I had hoped to
do backups to the pc rather than to those 8" floppies. Don't assume any
binary files other than data sets are handled properly unless you actually
try sending them back and forth.
