Hi Kyle,

I just started this yesterday, with the goal of having Matlab interface with GPIB-NET (not ENET/100). The NI-488 driver 2.5.5 lets me communicate with the ENET (although the instructions don't list it).
I was able to write a simple program, and achieve communication:

#include
#include
#include

char buffer[101];//

main ()
{
int gpib_dev1;

printf ("\nStarting GPIB test program.\n"); //Print the identification string read from

gpib_dev1 = ibdev( 0,26,0,10,1,0 );
//Use GPIB0 to access the GPIB device at primary Address 2, secondary address none, using
//10 second I/O time out, using EOI termination, and no special EOS byte for termination.

ibwrt (gpib_dev1, "*idn?", 5);
ibrd (gpib_dev1, buffer, 100); //This causes the GPIB-ENET to read back any
//data that the device at primary address 2 may
//have ready, up to 100 bytes.
buffer[ibcnt] = 0; //ibcnt is a global variable that stores the
//number of bytes read back or sent out by the
//most recent ibrd or ibwrt. We use it here to
//null terminate the buffer which holds the data
//we read back.
printf ("%s\n\n", buffer); //Print the identification string read from
//device at primary address 2 to the screen.

ibonl (gpib_dev1, 0);
// close gpib
}

with the following output:

Starting GPIB test program.

My next goal is to integrate with Matlab using MEX, with the starting point of the 1999 Matlab contributed MEX code:

I hope that helps.
