Just an update -- I have things working more-or-less OK now, after messing around with line terminations and timing.
However, there *is* a problem, at least on one of my systems. If you plug the adapter into the USB port with an active device on the GPIB side, things go nuts and that yields (at least with the Austron 2100F receiver I had on the bus) the every-character-typed-echoes-a-question-mark problem. If I connect the USB first, then the GPIB, that problem does not occur. I haven't yet figured out if a device clear or interface clear command will correct that.
