Subsequent to some testing in regard to the issue INES GPIB-PCI board: bugs
in ver. 4.3.4 and above, I have become suspicious of the implementation of
iblines in the ines driver.
To confirm or alleviate my suspicions would you please be so kind as to run
the following tests:
With a device capable of receiving commands attached to the bus please send
the output of
1) findlisteners
findlisteners: Scanning pads from 0 to 30 on minor 0
Listener at pad  0 (board)
Listener at pad  7
findlisteners: 1 device found.

and the following attached programme line_test.c.
2) line_test
ibsta 0x0120 ibgts
ibsta 0x0120 ibsic
ibsta 0x0120 lines 0x10ff
ibsta 0x0170 ibcac
ibsta 0x0170 lines 0x52ff
ibsta 0x0120 ibgts
ibsta 0x0120 lines 0x10ff

To compile the attached programme: cc -o line_test line_test.c -lgpib
If your ines board is not at minor 0 both programs take the -m option to
specify an alternative minor.
Thanks,
-Dave
