Tony talks about multiple readers of the serial port. Perhaps I'm
missing a point here. I don't understand how this is a desirable
thing in the first place. It strikes me that you need intelligence
to make multiple readers work correctly, so why not have only
a single open on the device itself, and have multiple readers talk
to the server that has the device open, so that the server can
incorporate the multiple-reader intelligence? Are there any circumstances
where you'd want to "blindly" have multiple readers on a single serial
port?
   I suppose that DNET provides a good example for a nice application
of multiple readers, but it has considerable intelligence in supporting
multiple logical streams. Does that illustrate what I'm talking about
well enough?
