5.

When you finish communicating with the device, make sure you put 
it offline using the 

ibonl

 command, as follows:

 

ibonl 0

The 

ibonl

 command properly closes the device handle and the 

ud0

 

prompt is no longer available.

6.

To exit Interactive Control, type 

q

.

The following special rules apply to making calls from the Interactive 
Control utility:

•

The 

ud

 or 

BoardId

 parameter is implied by the Interactive Control 

prompt; therefore it is never included in the call.

•

Except for reads, the 

count

 parameter to calls is unnecessary because 

buffer lengths are automatically determined by Interactive Control. 

•

Function return values are handled automatically by Interactive 
Control. In addition to printing out the return 

ibsta

 value for the 

function, it also prints other return values.

•

If you do not know what parameters are appropriate to pass to a 
given function call, type in the function name and press <Enter>. 
The Interactive Control utility then prompts you for each 
required parameter.

You can enter numbers in either hexadecimal or decimal format. 

Hexadecimal numbers—You must prefix hexadecimal numbers with

0x

. 

For example, 

ibpad 0x16

 sets the primary address to 16 hexadecimal 

(22 decimal).
