National Instruments NI-488.2 ユーザーズマニュアル

The 

ibonl

 command properly closes the device handle and the 

ud0

 

prompt is no longer available.

9.

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.

•

The 

count

 parameter to functions 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).

Decimal numbers—Enter the number only. For example, 

ibpad 22

 sets 

the primary address to 22 decimal.

You can enter strings as an ASCII character sequence, hex bytes, or special 
symbols. 

ASCII character sequence—You must enclose the entire sequence in 
quotation marks. 

Hex byte—You must use a backslash character and an 

x

, followed by the 

hex value. For example, hex 40 is represented by 

\x40

.
