If you have devfs enabled, you can say:

echo "hitk power" > /dev/tcp/localhost/2001

The only problem is that VDR takes a while to wake up after the connection 
has been established before it accepts SVDRP commands. Thus the above line 
will not work. You would have to sleep for a couple of seconds before 
sending the command. I haven't figured out haw to do this yet.

Another solution might be to use NetCat (the binary is called nc). I don't 
know how big the nc binary is (can't check right now). But again the same 
sleeping problem is present.

I'm sure there is a really simple solution for the waiting problem, it 
just hasn't occurred to me so far...
