I find minicim to be a pain and overkill in cases like that. I happen to have to do exactly what you are describing pretty often at work and I use picocom. It's simple, and there's not a lot of over-head. It's good that the switch came with the cable. If for some reason you needed to make your own, though, it's not terribly dificult. you can build sucha cable using the pinouts laid out here: http://www.zytrax.com/tech/layer_1/cables/tech_rs232.htm#db9

All you need to do to use picocom is specify the dev you want to use to connect with. e.g. picocom /dev/ttyS0
