NOTE. If you are using National Instruments NI-488.2 software you may wish to
select the buffer 1 mode to allow more comfortable viewing of the ASCII
response. Just type buffer 1.
1. To verify the system configuration, send the TABLE command to the Slot 0
Resource Manager and confirm the responses shown in Table 6. Your
configuration may not be identical, but the responses should be similar.

2. Verify the VX4801 VXIbus interrupt capability with the following steps:
NOTE. Make sure your Slot 0 controller and the VX4801 under-test are set to the
same interrupt level (see User Manual for location of interrupt setting). Also, if
you are using National Instruments NI-488.2 software, make sure Auto Serial
Polling is disabled to prevent the SRQ from being reset prior to a visual check.
a. Enable the generation of VXI Request True interrupt and force a VXIbus
interrupt with an error condition with the following commands:
