Nut upsuser - Oct 2006 - Unable to open /dev/cuad0: Device busy

Anyone know what is the problem for this?

thanks
Andrew


freebsd 540$ /usr/local/etc/rc.d/nut restart
nut not running? (check /var/db/nut/upsd.pid).
Network UPS Tools - UPS driver controller 2.0.4
Network UPS Tools - Generic UPS driver 1.32 (2.0.4)
UPS type: APC Back-UPS (940-0023A cable)

Unable to open /dev/cuad0: Device busy

  Current user id: uucp (66)
Serial port owner: uucp (66)
Serial port group: dialer (68)
     Mode of port: 0666

Things to try:

 - Use another port (with the right permissions)

 - Fix the port owner/group or permissions on this port

 - Run this driver as another user (upsdrvctl -u or 'user=...' in
ups.conf).
   See upsdrvctl(8) and ups.conf(5).

Fatal error: unusable configuration
Driver failed to start (exit status=1)

I have a unisys UPS, I probed the RS232 and notice that pin 2,  (receive data)
is going from -6v (OL) to 12v(OB), but I don't see the setting for the
genericups. Seems nobody else is using the RD pin?

Any driver I can use?

Thanks

Find out what is using that serial port?

fstat or lsof can probably tell you what process has it open.

Stopping a driver is an asynchronous process. Therefor, if you restart
NUT, you may attempt to start the driver again before the previous one has
stopped (and may still be locking the port). In that case, adding a delay
of about three seconds between stopping and starting is usually sufficient
to fix this. You can do this by adding 'sleep 3' in the startup script
between the stopping and starting of the driver, or alternatively stop and
start the driver from the commandline.

Best regards,
Arjen
