Something quite similar, . . . (probably a hassle to switch over) I had a
KVM switch, that permitted two computers to share one keyboard mouse,
monitor, and speakers. DE15, two USB ports and a headphone jack (IOGear
GCS632U?) It apparently watched for a hotkey from the keyboard to
activate switching.
I replaced it with one that had a physical pushbutton for switching (would
have preferred a DT switch, with visible positions, so that you know which
one is selected, not bouncing back and forth until it's what you want)

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
