I don't know of any simple (or even not-so-simple) way to do this with 
software. I approached the same problem in a quick-and-dirty way
by putting a spare terminal in the machine room, connecting a breakout 
box in the data line between the computer and modem and constructing 
a makeshift terminal cable that picks up the receive and signal
ground lines from the breakout box and feeds them to the terminal. 
Not elegant, but it is quick, cheap and effective; you will see
on the monitor everything going over the modem line.
