And BTW, the OS isn't watching the hardware lines, the device driver is
through the adapter.
If it's running on the CPU, it's running on the CPU. At GPIB service rates, the benefits of doing so at ring 0 are either nonexistent, or arise from suboptimal architectural decisions at the application level.
We're not exactly talking gigabit Ethernet here...
My tennis court must be an airport tarmac then, cause I'm talking to 15
devices, not counting the 42 relays and 10 buttons through the 6 50M30s
on the routing box
And your goal in attempting to control all of that with a low-end $150 GPIB adapter intended for plotter emulation and basic instrument scripting was what? To save money?
