This could be a good feature to add to the dahdi_maint utility.

You could add an additional context in the DAHDI_MAINT ioctl handler of your
base card to set/unset the yellow alarm bit in the framer. For an example, see
the Yellow Alarm handler in t4_check_alarms() and the DAHDI_MAINT ioctl handler
in t4_maint() in drivers/dahdi/wct4xxp/base.c

No. This will shutdown the entire card.
