I've got a half-dozen devices on the bus, and the behavior of ++auto 1 was
an issue. While it's convenient for continous readings from a single device,
it causes mass confusion with many. His new ++aread solves that issue. Just
remember to adjust the timeout to suit the device and measurement. With this
I can trigger multiple devices, then later go and collect the results.

Just completed testing Abdul's latest, and all the basic functionality looks
good, including SRQ and serial polls. He's been great to work with, upgrades
are very easy to apply, and progress has been good.

From much past experience, bear in mind there will still be some glitches
from a few odd devices, but that's the nature of the beast (especially HP
reciprocal counters). Now moving on to high-speed data transfer from
multiple devices, so I'll see how well things hold up.

I'd be interested in hearing about any GPIB/Prologix issues or questions
that I may be able to help with.
