.Sh HISTORY
|
|
The
|
|
.Nm
|
|
driver appeared in
|
|
.Nx 2.0 .
|
|
.Sh BUGS
|
|
The user-level interface to the gpib driver current doesn't do
|
|
anything useful.
|
|
The GPIB subsystem places the unfortunate constraint that the
|
|
local GPIB controller is always the controller in charge (CIC).
