   You could write a simple client/server setup to
   do that. Just listens on a TCP or UDP port for
   the correct sequence. For your app UDP might be
   the cleaner way, not as many hacks probing.

   Lots of sample client/server code on the net,
   Python and 'C'. I've built a number of useful
   things on those foundations. A non-blocking
   might be best, lets you dump odd 'noise' more
   easily. Python is pretty damned easy - but
   you've gotta encode()/decode() in order to
   deal with binary. 'C' and FPC have a 'timer'
   so you can break from the listening routine
   and do other stuff (outright or as a subproc)
   before returning to listening.

   The dead-simple client/server would do very
   well - you don't need threaded servers or
   forking servers or any of the other variants
   meant for higher volume traffic. That means
   a very small service routine. Just start with
   one of the sample 'echo' servers - where what
   you send gets reflected back - and it only
   takes a few tweaks.

   Bash and ksh have an obscure syntax for sending
   and receiving to a /dev/tcp pseudo-device - and
   I use it in several scripts. Probably THE easiest
   way for what you're trying to do. Would not be
   limited to a LAN either if you put the right
   rule in the firewall.
