The MakeDevice command creates a new temporary Driver488 device that is an identical copy of an
already existing Driver488 external device. The new device is attached to the same I/O adapter of the
existing device and has the same bus address, terminators, timeouts, and other characteristics. The newly
created device is temporary and is removed when Driver488 is closed.
KeepDevice may be used to make
the device permanent. To change the default values assigned to the device, it is necessary to call the
appropriate configuration functions such as
BusAddress , IOAddress , and TimeOut .
