[Coco] [coco] Piping in OS9?

[George Ramsower]

How would I make OS9L2 pipe everything from one serial port to another---  
back and forth.

What I want to do is communicate with another coco through the coco that is 
already connected to this PC.
 The coco which is connected to this PC has three com ports. The other coco 
does not have a com port, at this time. Once I add the port and connect it 
to the middle coco, I would like to be able to communicate with it.
