troubleshooting instructions.
Troubleshooting ibtsta Messages
If
ibtsta
fails, the program generates error messages that appear on your
screen. These error messages explain what went wrong when you ran
ibtsta
, and describe how you can correct the errors.
For example, the following message might appear on your screen if you did
not disconnect all your GPIB cables:
The fact that the ENOL error was not received when
expected indicates the possible presence of other
devices on the bus.
Please disconnect ALL GPIB cables from the GPIB board,
then run this test again.
The following message might appear if the
/dev/gpib0
special file is not
present:
The special file /dev/gpib0 cannot be found.
In this case, or in a similar case in which device special files are not created,
verify the following:
•
Make sure that the GPIB driver is installed.
•
Verify that you built a kernel with the driver and that you booted the
system from the new kernel.
•
If the two previous items are correct, run the system utility
kmknod
by
entering the following command:
/sbin/kmknod
