Whenever I get random junk on the screen it means that I haven't set up my serial connections right. Try messing with the error handlings / encodings. You'll get there.

I'd also boot from a live CD and try minicom from there. This way you can verify the settings and that your board works, then move back to windows and try to replicate it.

As a newby when the first one fails then you really feel alone, so some opinions that may or indeed may not help at all ...

Were this me I'd wager it was a baud rate issue and that your term was not working ...
For me winders is a lunar landscape, bare airless inhospital to life, I'd boot one of the live linux CDs eg say ubuntu 10..12 anything and run minicom.
It's definitely 115200 8 1 and the <funny characters> say it is surely working

in general 1 or 2 chars say baud rate is set too low
lot of funny chars say it is set too high

(booting a live CD does not touch your disk, so is totally harmless)
