This problem does not relate directly to the Amiga, but it is
technical and I do own an Amiga ... besides, I didn't know where
else to post it.

I now have two things that require connection to my serial port
(modem and X10 controller) and this is a problem.  I would like to
build a switch box so that I can connect both devices to it and
JUST FLICK a switch to select one.  Unfortunately I do not really
know how I can do this.  My first thought was to use a couple of
multiplexer chips and multiplex each line ... but I am not sure
if that will allow two way communication.  Also, this would require
each line to be multiplexed.  Do all the lines have to be switched?
Can I just make each line connect to both ports and just have one
line multiplexed ... say a certain line that tells the device he
has the port.  Is there such a line on my serial port?  I read the
description of the pin-outs but did not know what some of the pins
meant.  I would appreciate any input into this.  Thank you.
