A search for
de9 to db25 rs232 adapter
Turns up many of them for cheap. A computer shop that's been around long enough
ought to have one or more laying around, might even give it to you to avoid
throwing it away.
Irritating that companies for whom cables are their specialty are using the
there-is-no-such-thing term "DB9". The 9 pin D-Subminiature connector size is
the E size, also used with High Density for analog monitor connections with 15
pins. Commonly called HD15 but should be HDE15.
The B size is is used for 25 pin serial ports, PC parallel ports, old Macintosh
SCSI ports, 13W3 connectors for old Sun monitors and that one has been used
with gas and liquid connections run through the 3 holes Sun used for coaxial
cables.
The A size with 15 pins was used on joysticks for PCs, the Atari 5200 game
console, and old Macintosh computers for their monitors. Don't plug an old Mac
monitor into a PC gameport. Don't, seriously, do not.
Of course Apple had to come up with their own variant with 19 pins. Whomever is
responsible for maintaining these things never bothered to give Apple's 19 pin
external floppy connector a letter designation for size. It's also used on some
obscure industrial equipment or something. After the connectors being out of
production for a while, with old stock supplies completely gone, the guy who
makes solid state floppy emulators for Macintosh and Apple II computers got
together with some company that makes stuff for whatever odd non-Mac stuff uses
that connector. They had a new production run made. For a short while the Big
Mess-O-Wires guy had the world's entire supply of new 19 pin D-Sub connectors
on his back porch.

Yes and no Greg. They are all db9's and this sniffer is db25. I have the
fdti cables, but not a spare 9 to 25.
I'm more concerned that this testing's java is way to new.
