[Nut-upsdev] Megatec driver FR: repeat shutdown

[Andrey Liakhovets]

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
