> Greetings,
> I am the developer of the Prologix GPIB-USB board. Recently, I came
> across some posts in this newsgroup about the difficulty of configuring
> the virtual serial port to communicate with the controller - especially
> getting RTS/CTS flow control working just right on Linux. As someone
> who believes in developing devices that "Just Work", I take such
> feedback seriously. Thank you.
> 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.
