Package: nut
Version: 2.0.1-4angels2
Followup-For: Bug #327072
I am running sarge and encountered the same problem as maciekc but found
a different solution. I edited /etc/init.d/nut to not stop upsdrvctl if
the POWERDOWNFLAG flag was set (patch below).
I think maciekc solution is more elegant and I am using it but the only
point I would raise is that my sarge ttySx ports were configured by
default to hang up when upsdrvctl closes the port.
Since several of the UPSes defined in genericups.h receive a shutdown
by: "lower DTR" and "drop RTS", the UPS may incorrectly shutdown early
when upsdrvctl terminates for the first time.
I considered inserting an:
stty -F /dev/ttyS1 -hupcl
in /etc/init.d/ somewhere but this meant the serial port used by nut was
defined in two places.
Instead, I have modified upsdrv_initups() in genericups.c to clear the
HUPCL flag on the port (patch below).
I don't have the background knowledge of ttySx port usage to know if
this is the correct solution so attached it here for consideration.
