Is there some reason you want to access the 7210 directly rather than
using the Linux-GPIB library and driver?

    http://linux-gpib.sourceforge.net/doc_html/index.html

I've successfully used that with several ISA, PCI, and PCMCIA cards,
including one that was 7210 based.  My most recent use was to talk to
HP 9144 and 9145 cartridge tape drives.

To act as a device rather than the controller, poll ibsta() and use
the returned status to determine when the controller wants you to
talk or listen.
