Part of the problem is that there is no THE WOL package as there are
different forms of WOL and their packages.

One way is using UDP port 9 as you said. I was using the script below to
do so (using socat) but I can tell you that this method doesn't work for
all devices.



# The magic packet is a broadcast frame containing anywhere within its
# 6 bytes of all ones (FF FF FF FF FF FF in hexadecimal), followed by sixteen
# repetitions of the target computer's 48-bit MAC address.
for ((CNT=0; CNT < 16; CNT++)); do

echo -en "$MAGIC" | socat -T1 -u STDIO \

Kind regards,
