Interesting. I used to sell a GPIB-RS232 version some years ago. Sales were low since customers were clamoring for an USB version! But then I hadn't discovered this crowd :-) Happy to take another look at it.
I am in the process of designing a GPIB-Ethernet controller. You think that will be of any interest?

While the USB version works OK for my application, an RS-232 version that had an identical API would be very useful.
