Data Connect Enterprise, Inc. Asynchronous Null-Modem Adapter Model 6A

Data Terminals don't want to talk to each other! Neither do Personal Computers or serial printers! They will only talk to modems (DCEs), not to each other (DTEs). But these devices can be fooled into thinking they are connected to modems when they are not. Our Null Modem Adapters (sometimes called async. modem eliminators or cross over cables) will do the job.
