The Most Compact n/m Adapter
These adapters (as sold by dgjiachen) conform to the "Full Handshaking" pinout described on Wikipedia (search for "Null modem"), so by-and-large will work with normal serial ports without any special settings. I have used one to connect a PL2303-based USB serial adapter to the serial port of a server so that I can do some startup troubleshooting via the console. Took advantage of the twin pack, as one shall inevitably go walkies when surrounded by envious techies curious about how I make fixes as close to the metal as possible...

Keep one with your usb-DB9 adapter
There are lots of serial devices wired to expect a modem connection, including most usb-db9 adapters. This is just what was needed for programming up my firewalls

Not female to female
This is male on one side and female on the other. This means it will not change the gender of your initial plug.
