I asked our hardware designers and this is what they told me. This subject
apparently comes from an old MIL-spec.

The first letter refers to the shape of the shell. As far as I know, there
are no other shapes.

The second letter refers to the size of the shell (i.e., A, B, C, D, E).
According to our designers, there never was such a thing as DB-9. Your
reference to DB-9 should probably be DE-9 for technical accuracy. However,
due to general misuse, the incorrect term is becoming part of the
vernacular. Another common connector is DB-25, used for EIA-232
connections. A "DB-9" connector would have 9 pins inside a shell large
enough for 25 pins.
