5.4 THE EXTENDED HIU COMMANDS
The Extended HIU commands enhance the original TIWAY I Host Adapter
command set by providing improved performance and operation. Some of the
functions provided by these commands are the definition and operation of
macros, HIU bandwidth adjustment, and the reporting of network status and
statistical information. These commands will not be accepted by any UNILINK
Host Adapter that is configured to emulate a TIWAY I Host Adapter or NM or
SANM.
