Argh!  Not to pick on this post - or poster - in particular; I've just
been seeing this mistake over and over, and it's finally gotten to the
"minor rant outburst" point.

That is not a DB9!  The DB shell is the size used for 25-pin
connectors; the size used for 9-pin serial is the DE shell.  (DA is the
15-pin size used for peecee joystick ports and AUI Ethernet; DB is the
25-pin kind used for standard serial ports and peecee parallel ports;
DC is a 39-pin size most people rarely/never see; DD is a three-row
50-pin size used for Sun-2-era SCSI and nothing else I know of, though
there probably is something; and DE is the size used for 9-pin serial
and 15-pin "VGA" video.  Other sizes exist, such as the 19?-pin size
used by NeXT video, but as far as I know they don't have Dx names.)

I have never seen a DB9 - a connector designed with only nine pin
positions in a DB-size shell - and, while I would hesitate to say no
such thing exists, it certainly is very far from common.
