> The good news is the new version of the GPIB-USB controller (firmware
> version 4.2 and above) eliminates the problem completely. Thanks to
> a better USB chip, none of the serial port parameters matter anymore;
> they do not have to be configured and can be left alone.
> The not-so-good news is you need the new hardware.
> I recently saw your comments in Nuts & Volts magazine about
> Prologix GPIB-USB controller. Much appreciated. Thanks!
> FYI, we recently released an updated version with metal enclosure
> and some other improvements.
> * Metal enclosure for durability and reduced EMI
> * Screws to mount unit on instrument
> * Higher performance by using faster USB controller
> * Simplified configuration in software; no DIP switches
