I made a bunch of various such cables back in the 90s, and three-wire doesn't always get the job done.
Not everything I had to connect used EIA 232 (RS-232). All of our terminal servers were from DEC so EIA 423 (DECconnect) was most common and there were also some others.
Eventually I wrote up a Word document with all the pinouts I knew and the types of cross-wirings I had to make. I still have the document, but some of the diagrams are missing because I hadn't inserted them properly.

The last time I had to make such a cable was to connect a DB9 RS-232 USB adapter to the MMJ DECconnect console of one of my AlphaServers and it didn't work reliably as three-wire. It doesn't help that the MMJ console port is flaky.
