Let's see.  To do that, you'd have to set the logging program up to 
record the time interval via the GPIB port, and then get the correction 
value via the serial port, then apply the correction and log the data.

Well, there's my project for this weekend...

(Actually, for my real purpose which is measuring the offset of the Rb, 
it's not worth the effort since I'm averaging over many hours, but it 
sounds like a good "science fair" project!)
