Im using W98 with a N.I. GPIB board thats communicating to
a Hp1672d (Logic Anaylzer).
According to HP manual, it expects a termination character (Linefeed)
after every "query".
But good news is, I found the problem, and perhaps, one of you
guys knew about this, apparently, Labview has a problem with
GPIB file transfers of over 900K.
So, I broke up the 12M data into 800k blocks and everything worked!
Thanks,
Eric
