I may have to make a rather unpolished serial port snooper for 
in-house debugging use. But before I do, fearing reinvention of the 
wheel, I thought I'd ask if anyone know if such a program existed as 
shareware or freeware.

About 7-8 years ago I found and downloaded one of these, but don't 
seem to have it any longer and so far haven't found one in searching 
the web. But who knows, maybe one is out there.

The common Mac has two serial ports; for this never mind one-port 
powerbooks and the new USB Macs. I minimally need to have this 
snooper show all communications on both ports, both acting as input 
ports. Then I can connect these between another Mac (or PC) and a 
connected serial device like a modem. The snooper is a "wire tap" 
device that records both sides of the I/O.

Ideally the program would support triggering to start and stop 
recording, but that is not vital. (Triggering is defining one or more 
bytes in a sequence to watch for, and if present, to use it to start 
or stop the display buffer filling. It is somewhat like a trigger on 
a logic analyzer or oscilloscope.)

Of course it needs to have some serial port options like baud rate and parity.

If none exists and I have to roll my own "wheel", what is the maximum 
receive speed that I can expect a Quadra-series Mac to receive via a 
FB application? Will it reliably grab 28.8 or 38.4 kbps? Two ports at 
once? Any special FB tricks to watch for?

Thanks for any suggestions.
