Thanks Tedd, I checked out the web site and corresponded with the 
author. It is not quite what I was seeking and is a considerable 
compromise. It is intended to watch the in and out paths of a single 
port on the same Mac that is running another application using the 
same port, like a e-mail client or web browser.

I am seeking an application that watches the input channel on two 
serial ports, so that the Mac running the application must be 
connected to another computer (Mac or PC) that is tied to a device 
like a printer or modem, using a special cable. We're not concerned 
about the extra Mac or cable (we do hardware design work), but the 
way to do the snooping.

Peter Lawton, of Always Thinking said this, in addition:

I haven't searched for it yet, but that is another possibility.

Thanks,

Ray
