Comedi, no.  "or some other method", yes.  We're using a GPIB card from
National Instruments to talk to instruments over GPIB.  The card comes
with a DLL for Windows (also avail for Un*x I believe) which we wrapped
with the calldll module.

If there's a DLL, you can wrap it and use Python for all the high level
stuff.  

Don't count on any kind of hard real-time performance, of course, but
dang if it isn't the easiest way to control external hardware that I've
ever seen! :)
