Hello. In continuation to http://lists.alioth.debian.org/pipermail/nut-upsuser/2007-June/002880.html Inelt Monolith II 1000 (don't know about LT) actually requires sending shutdown command twice, with delay of 5 to 8 seconds, according to my experiments. The attached patch enables the megatec driver to repeat shutdown command with configurable delay (cmdrepeat, in milliseconds). Default cmdrepeat value (=0) keeps the current behaviour, single shutdown command. Package ftp://ftp.altlinux.org/pub/distributions/archive/Sisyphus/2007/04/15/files/SRPMS/nut-2.0.5-alt2.src.rpm + the patch + ups.conf below [inelt] driver = megatec port = /dev/ttyS0 cmdrepeat = 5100 works with Inelt Monolith II 1000 on ALT Linux 4.0 Terminal updated to branch/4.0 ( http://en.altlinux.org/ALT_Linux_4.0 ). Besides "the old bad" N-Power SVL-600 works with the patch! (for example, with cmdrepeat = 1500) Unfortunately this patch is for old version of nut, and is bloated with some support of minute's fractions for shutdown delay. FR: Is it possible to have similar functionality in the nut mainstream code? Best regards, Andrey Liakhovets -------------- next part -------------- A non-text attachment was scrubbed...
