From my old BBS days, here's how a null modem works. Say you had two telephones called up to two other people. If you wanted to you could put the two handsets together and the two people could talk with each other. Of course you would have to flip one phone around so the ear piece went to the mouthpiece and vice versa. This is what a null modem does. It takes the 'send' line from one device and crosses it over to the 'receive' line on the other device and vice versa.
