[Linux-gpib-general] problems with RH 9.0 and Measurement Computing PCI Board

[Neil P. <np...@ex...>]

Hi All,

I've used GPIB/HPIB a lot in the past (>5 years ago). Subsequently I've 
done a lot of work with Linux (at SGI).  I'm now trying to get the 
Measurement Computing PCi Board to run with RH Linux 9.0 ... I'm getting 
everything to work just fine for make etc.  Even insmod/modprobe 
installs the cb7210 module OK (checked using lsmod).

BUT, when I try ibtest I get the strangest result ...

> [root@localhost examples]# ./ibtest
> Do you wish to open a (d)evice or an interface (b)oard?
>         (you probably want to open a device): d
> enter primary gpib address for device you wish to open [0-30]: 2
> trying to open pad = 2 on /dev/gpib0 ...
> Segmentation fault

I checked the code for the changes in cb7210 etc and I guess everything 
is up to date in 3.1.93 ,,, so I think I must be doing something silly 
... any body have any suggestions ?
