No, this did not fix the problem. Here is what I get first with 1, then with 255 in the third argument...

Hi Zen,
Please try adding the asynSetTraceMask command to your st.cmd right after the vxi11Configure command.
vxi11Configure( "L0","134.79.64.25",0,0.0,"gpib0",0,0)
asynSetTraceMask("LO",0,1)
That will force a connection to the controller before iocInit. See if it helps. If it does not help then change the line to:
asynSetTraceMask("LO",0,255)
so we can get a complete printout of what is happening.
