What kind of console cable for these 3COM switches? Pinout included

[003]

I picked up a pair of 3COM SuperStack III 4400 SE 24-port 10/100 switches for free. I have no idea about their current configuration. I want to get a console cable to gain access to the CLI and try to reset the configurations back to default, and then just mess with them, build a test lab, etc...

My computer does not have any serial ports, but the console cable connection is a male DB-9 connector.

I found the following cable online:

FTDI is from what I have heard, the best serial to USB adapter chipset. But that particular cable uses a male DB-9 connector, I need a female connector. Of course there are simple adapters, but I am wondering if the pinout will be identical to work with a simple adapter.

Here are the console connection pinouts usable by the switch:

I am confused because I thought a null modem cable is DB-9 to DB-9 but the documentation for the switch indicates it is DB-9 to DB-25?

What about the middle option, the PC-AT serial cable? Will the cable I linked to above work as is, with a simple male to female adapter?

Any help is much appreciated!

I can provide any additional information on request!

The DB-25 Is a modem connection to the Db 9 which is for your console. Unless you have one of those computers with the modem port still around, this will not be too useful for you.

Try the cable above but I make no guarantee that it'll work!
