Not for the speeds I need :-)

Not quite but a lot of it yes.  The NI command set seems to be simply
wrapper functions of the 7210 chip anyway...

I've never spent much time on it, I found some data sheets on some

And here we go again :-)

As much as I'd personally love to have GPIB in FreeBSD, I just don't
see it having enough mindshare and marketshare to happen.

I'd love to be proven wrong...
