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."
