How to get a USB-Serial connector working

I have a laptop with only USB ports, I'm trying to get a USB Serial connector working. I can't find a good guide on how to do it, I can figure out that i need to enable some sort of kernel options, but I'm not sure about how to go about doing it. Can someone hold my hand and tell me what I need to do to get it working?
Thanks
It depends on what kind of USB->Serial you have. Some common ones are:
cp2101
ftdi_sio
pl2303
And those kernel modules are all included with Arch (along with lots more).
I'd start by just plugging it in and running dmesg to see if your kernel/udev detected it. If you see something about ttyUSB0 then you got it. Just open that device as you would open a normal serial port.
If it doesn't report anything, run lsusb and see what kind of chip it has.
If it does report it, I would use minicom to interact with it.
(Run "minicom -s" as root and set the device to /dev/ttyUSB0, baud to 9600 (or whatever) 8N1. Turn off Hardware and Software flow control. Finally go into Modem and Dialing and delete the init line (unless you are actually dialing)).
