It probably depends on your version of Dynix. When I recently installed a Sequent Symmetry with Dynix 3.0, we indeed needed four wires, since I could not find any way to turn of the carrier detect. If you get Sequent's System V port (Dynix/pts I believe), you might be able to turn it off. Of course, you can also fake it in the connector by connecting the DTR output to the DCD input. By the way, you may actually *want* four wires. It has the very attractive feature of automatically logging you out if you turn off your terminal, which is good for your security. Besides, it usually saves processes.
