Does anyone know of a freeware and/or open source program for analyzing 
serial communications?

What I am looking for is a program that uses the RX line on two separate 
serial ports and a special 'tap' cable to monitor both the RX and TX lines 
of a standard serial port. I want to be able to view the communication in 
hex, preferably with byte-by-byte timestamps. Extra points if the software 
can save an interaction to disk and reload it to view later.

Thanks,
