I think it just clicked. I had already read that page but i missed 1 important thing. I was confused because it seems that 1 change of state can represent more than 1 bit of data. I just noticed on that wiki page that it says "a symbol may have more than two states".

As far as i knew there were only 2 states in serial. Thats what im using anyway so yeah, as you say "In your simple application baud = bps". I am also using 8N1.

Thanx for your help. I can make more reliable calculations now
