The driver design does not fit in my wish list too. At least I want a real bus abstraction. It doesn't even support multiple channels it seems. > _IF_ we want IEEE488 support, we want it so that it conforms to the > industry-standard API and/or supporting SCPI.

My knowledge about IEEE488 came from Commodore systems - don't know how much their usage fits into industry-standard API - at least it has nothing to do with SCPI. > You are welcome to pick up http://phk.freebsd.dk/patch/GPIB.tgz and > work from there.
