How are they interfaced with ECS?? Serial Port??

I had built some displays with keypads years ago. I also built a device
that would interface many (as many as you would like) of these displays
into ONE serial port. The keypad would send ECS macro values. I would
use the serial byte item to receive these values then set a macro
accordingly. I would also use the serial byte item to send messages to
the display. The top line of the display ALWAYS showed the current date
and time.(From ECS) the other 3 lines scrolled reminder type messages.
By using the serial byte item this can get a bit programming intense but
it actually works very well. The only downfall about the interface that
combines ALL the displays into ONE serial port is that only ONE keypad
can be active at a time and ALL of the displays will show the SAME data.
