Interactive Control Syntax

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.

Number Syntax

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).
