The correct technical designation for a D-sub connector with nine pins is DE9.
It’s early and eyes are still a little blurry, but I’m not seeing a cite?
Wikipedia fleshes it out a bit:
The D-sub series of connectors was introduced by Cannon in 1952.[3] Cannon's part-numbering system uses D as the prefix for the whole series, followed by one of A, B, C, D, or E denoting the shell size, followed by the number of pins or sockets
No links to a primary source, but seems plausible.
