It needs to be a serial modem the graph link is a 25 pin serial not paralel you cant intermix them _J:_e.r_ wrote in message ... Hello, I have a question. I have Zterm and the graphlink and a modem. Now, if my modem has a parallel port on it that is female, as does the graphlink, wouldn't it work with just a male-male adapter (female to female)? What is this about a null modem cable? -Jeremy
