Asserting the SRQ Line in LabVIEW

Primary Software: LabVIEW Development Systems>>LabVIEW Base Package
Primary Software Version: 8.2.1
Primary Software Fixed Version: N/A
Secondary Software: Driver Software>>NI-488.2

Problem:
I'm developing a GPIB application that acts as an instrument and not as a controller. I need to assert the SRQ line. How can I do that in LabVIEW with NI-488.2 VIs?

Solution:
It is possible to set any status bit of the 488.2 by using the rsv command. The address 0x40 ( ASCII @ ) corresponds to the Service Request . By using the GPIB Misc function, it is possible to assert the SRQ :

rsv = Command to set the status byte
@ = Hex value 0x40, which equates to the Service Request bit.
