In the past there was this nice document G1530-90360 listing the whole set of serial command to run the old gcHP-Agilent 6890 outside Chemstation.
Now I'm working with a gc 7890B and it would be very useful to have the same set of serial command to use as for the old 6890; is there a reference manual/document available? or is the old version running also with the 7890B (I've tried but it seems they don't work, at least not in the same way!)
thank you
