not that it's easy but a raspberry pi could be set up to watch the serial

Hello all,
I am looking for a device that sits transparently in an RS-232 serial line
and upon seeing a particular code go over the serial line ((or sequence of
codes) will actual a relay (or a transistor). Something with two DB25s or
DE9s and is configurable to what code will trigger the output? Some kind
of
box?
Does anyone know of such a thing? I guess it could be cobbled up with a
microcontroller, but hoping to just get something "off the shelf."
Thank you
