How can CVI work with the I-SCPI from HP?

I am using Labwindows/CVI to programme some modules from Agilent and the controller is the HP8491-1394 fire bus.I want to control some registered based instruments using the SCPI command.So,I installed the HP VISA and the I-SCPI,if I use HP VEE to send a "*RST" text,the device reponsed ok,but if I use CVI to viWrite the same text to the device,it reported an err said the device did not support the command.can somebody help me?thanks

If the device is register based, then the message based operations like viWrite are not valid. I-SCPI simulates this by knowing what specific registers a given command corresponds to. The only way I know of that HP/Agilent allows you to communicate to these is by using their instrument drivers. That I-SCPI knowledge is also built into VEE, I imagine.
