My company is interested in getting an RS-232 monitor box. I remember seeing
some software packages available that do this through a PC. Are these "toy"
programs or will they on the level of the Spectron D-584 scope:

	o Monitoring of both sides of a full-duplex connection at selectable
	  speeds. Must handle at least 9600 baud.
	o Some sort of intelligent way of seeing the timing interaction 
	  between the two ends (the 584 uses alternating lines of the display).
	o The ability to capture data based on various signatures -- certain
	  data strings, parity errors, etc.
	o An interface that causes minimal signal loss.

Finally, the program should have the ability to record the data on disk. 

Any leads? Alternatively, are there custom boxes that do this in the 3-5K 
range? Thanks.
