Thanks Marv,

Well I was first thinking I'd keep things nice and simply so all a user has
to do is select a pin and then bring it down to ground when he closes the
switch.  There are many ways one could employ to get more than 10
inputs/outputs out of 10 pins.  At the moment I could have any of the pins
as inputs or outputs but I guess my first version would just have inputs.  I
was thinking that from an installation point having one controller per panel
would make things easier.  What I am mainly interested in is how to manage
more than one of these things in software on the PC.
