You need to run the 'gpib_config' utility to setup the driver before
you can use it. In order to do it automatically you can add to your
start script something like this (supposing the appropriate driver
is loaded on the startup):
\n
gpib_config --minor 0
\n
To give a user access to the computer's gpib board you will have to add
them to the group 'gpib' or, you could change the permissions on the device
files /dev/gpib[0-15] to something you like better, using 'chmod'
\n
Edit /etc/gpib.conf to match your interface board, and any devices you wish
to open via ibfind(). See the documentation in /usr/share/linux-gpib/html for
more information.
\n
"
if use pcmcia; then
DOC_CONTENTS+='
For PCMCIA cards:\n
All files needed for a PCMCIA board were copied to /etc/pcmcia.
You may wish to edit the options passed to the gpib_config call in the
/etc/pcmcia/linux-gpib-pcmcia script.
You may need to send a SIGHUP signal to the cardmgr daemon to force it
to reload the files in /etc/pcmcia \(alternatively you could use your
pcmcia init.d script to restart the cardmgr, or you could just reboot\).
The driver module will be loaded as needed by the cardmgr.
'

if use firmware; then
DOC_CONTENTS+='
For Agilent \(HP\) 82341C and 82341D cards:
The firmware for these boards is uploaded by passing the appropriate
firmware file from /usr/share/linux-gpib/hp_82341 directory to
gpib_config using the -I or --init-data command line option. Example:\n
gpib_config --minor 0 --init-data /usr/share/linux-gpib/hp_82341/hp_82341c_fw.bin
