"magic sys request" executed by command for remote installation/administration

I need a "magic sys request" executed by command an not by keys because
of remote adminstration.

how can I hack such a feature? Kernel specialists?

Via serial connection you can send a BREAK which will be
interpreted from the system as if you'd press magic sysrq.

solution: echo b >/proc/sysrq-trigger and perhaps a umount before:
echo u >/proc/sysrq-trigger
enable magic sys req first: echo "1" > /proc/sys/kernel/sysrq.
