To add a few more comments, then.
First of all my favorite nitpick: It's a DE9, not a DB9.
The second letter is the size of the connector. And you're talking about
an E-size connector.
Second - if someone gets a few MMJ connectors and a 6-wire cable, crimp
both ends and getting a MMJ to DE9 is also an option.
You can find them on Ebay, and probably other places as well. Makes for
a much easier setup than soldering pins.
There are also MMJ to DB25 adapters out there.
