Stan,
I forgot to mention that I tried both the hp894xx.cid and hp894xx2.cid
VEE drivers. They both have 5000+ lines of entries for center
frequency command.

Stan,
I am trying to control an HP89441A Vector Signal Analyzer (VSG) using
HP-VEE running on an HP700i UNIX work-station. The work-station is
able to commuincate back and forth with the VSG, but it takes a long
time to execute a commnad.
I attached the HP-VEE supplied HPIB monitor to a component driver to
view the activity on the HPIB while the work-station initiates a change
center frequency command to the VSG. The HPIB monitor recorded >5000
lines of entries prior to completing the command. The same command
takes 10 to 15 lines of entries using direct I/O. This phenonmenom was
not unique to changing center frequency only. It is also true for
changing instrument mode and other commands.
The component driver seemed to be checking for errors in the VSG and
setting up some kind of calculations during this 5000+ line entries.
Do you know if there is a way to disable all those error checking
features when I know that the center frequency is valid for the
instrument?
Thanks for your help in advance.
