A lot of network devices has a terminal RJ-45 socket, which is usually a simple COM-port. So, to configure such a device, you have to connect RJ-45 socket to PC's (or terminal's) DB-9 COM-port. Documentation usually says: "use the terminal cable, provided with the device", and then the awful discovery shows up: "Hmm... uh... terminal cable? That tiny little thing, which I threw out just after buying the device five years ago?"
The only way to patch situation up quickly - to use handmade cable, which you could do in couple of minutes, knowing the propper pinout.
So that is the case, which terminal cable pinouts for such things as CISCO or D-link devices do you know?
