Hello,

A question: 5 different devices use RS 232 as a communication protocol =
to/from a controller (or PC). I need to combine those lines to ONE RS =
232 line.=20

One way to do it is to use 3 PIC's with dual ports (or 6 single port =
PIC's) or makbe "bit-bang" data, make up a que, and let one port become =
the "compressed" data stream further down the line.

however...

=CF have tried to find a commerciallay available box that is doing this =
magic tric - and almost suceeded. I don't have time to design the thing, =
and wonder if anyone out there know where I can buy one :=3D)

NOTE: It must be a separate box. A multiple RS 232 comm card to a PC =
doesn't count.

Any hint appreciated. Thank you.
