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: >We have heard of a program called "Serial of Champions", and even found the >author at one point. That was about a year ago, I think. But we've never >been able to find a copy of the software on the Net. (I was no longer >looking when I found the author.) I haven't searched for it yet, but that is another possibility.
