After Sending the SYSRESET Command to a GPIB-VXI/C, All Subsequent Commands Return ENOL (No listeners found).

Hardware: GPIB>>Plug-in Controllers>>GPIB-VXI/C

Problem:
After sending the SYSRESET command to a GPIB-VXI/C, all subsequent commands return ENOL. What is causing this?

Solution:
This is happening because the GPIB-VXI/C needs some time to rerun RESMAN after the VXI reset. Wait until the sysfail light goes off and then a few more moments (after the sysfail goes off, there is some time needed for RESMAN to run) and then try a GPIB command (e.g. ibwrt "*IDN?") to the GPIB-VXI/C. Also, check for the GPIB-VXI/C configuration. It might be possible that the wait period (wait for sysfail to be removed from a vxi backplane) is set to larger than normal values (5 sec...).
