Monitoring GPIB Ports

Hi,
I have 2 Instruments that are communicating with each other via a PCI - GPIB Cable. I have National Instruments Driver Installed on my PC. I wanted to develop an application that could read from the GPIB port in one PC and log them to a file. The system, I am planning to run the program runs on Solaris OS 2.5.1. There is a s/w developed by National Instruments called the NI Spy to log the info in Windows OS, but there are no solutions for Solaris.

I would like to know what is the best way to tap the information provided I have root access. Is it possible to read from a memory address continuosly ? . I am not vey sure of solaris OS, but I believe that direct I/O access is not allowed unlike in Linux as root. Could anyone help me with this and tell me how I could go about capturing the data.

Thanks in advance
