Congratulations on getting the link working and on making a null modem cable, which once was almost a data comms rite of passage!
The RS-232 standard has had wide influence in naming conventions over the years, but it is concerned with connecting a computer (DTE) to a modem (DCE). Manufacturers also vary in how which signals they implement which has led to many sales of breakout / patch boxes over the years.
My rule of thumb is if it says modem on the box it is DCE, otherwise it is DTE and to connect two DTEs together needs a null modem cable which pretends to be two modems talking to each other and swaps the signals over. People tend to forget they know this though...

Edit: I've added a summary of this thread to the since there are many adapters on the market.
