[Elecraft] D-Connectors and DIN Connectors

[JT Croteau]

and to nit-pick some of ya'll even more.  What most folks, and even
industry professionals call  a DB-9. (typical computer connectors) are
actually DE-9.  DB-9 is a common misnomer for the DE-9 (a true DB-9
connector would have 9 pins in a connector the shape and size of a
DB-25, the other 16 pins would just be missing).

D-subminiature connectors were invented by ITT Cannon , part of ITT
Corporation in 1952. Cannon's part-numbering system uses a D as the
prefix for the whole series, followed by a letter denoting the shell
size (A=15 pin, B=25 pin, C=37 pin, D=50 pin, E=9 pin), followed by
the actual number of pins, followed by the gender (M=male, F=female).
For example, DB25M denotes a D-sub with a 25-pin shell size and 25
male contacts.
