PC-to-PC Communication through GPIB with LabVIEW 7

Primary Software: LabVIEW Development Systems>>Full Development System
Primary Software Version: 7.0
Primary Software Fixed Version: N/A
Secondary Software: Driver Software>>NI-488.2
Hardware: GPIB

Problem:
I want to establish PC-to-PC communication through GPIB with LabVIEW 7. I have tried using several different KnowledgeBases articles and the GPIB manual but I still can not communicate with the second PC. I keep getting the no listener error.  What am I doing wrong?

Solution:
If you are getting the no listener error it means that the non-controller interface is not active.

Here is the sequence of commands you can use. Check the Sequence-file in the zip-file below.

Step	Controller	Non-Controller	Comments
1		ibfind gpib0
2		ibpad 2	(set address to 2)
3	ibdev 0 2 0 13 1 0
4	ibwrt "Hello"		(This function should not return immediately)
5		ibrd 100
6	ibrd 100
7		ibwrt "response"
