I don't think there is any way to tap into the serial port the way you 
want. Besides the 'low tech' method, I believe the only 'high tech' 
method is pretty much the same. Create a virtual port, log the data as 
it comes in, and then forward it on to the real port.

Creating a virtual serial port is not trivial, so if this is a one-off 
job, I'd use the low tech method. You don't need another PC though, just 
hook up 2 usb serial port adapters (about $20 each), hook up a null 
modem cable from the original port to one of the new ports. Write a 
simple app to read from the new port, log, and forward off to the second 
new port.
