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